Author Response
Reviewer 1:
The paper addresses problem of self-medication for ophthalmic conditions in a
developing economy, which is relevant from the point of view of health care.
- In my opinion, the message of the paper will be conceived by the reader with
difficulty. The English language is to be fine-tuned (my native language is not English,
hence opinion of other reviewers in this regard should be considered accordingly).
- Thank you for this comment. We have now addressed this point and checked the language of the study.
- It could be of value if authors include the questionnaire in the text as a table or as an
appendix.
- Thank you for this comment. We have now addressed this point and added the questionnaire tool as appendix.
- Line – 25-26, 88. What type of surgery the authors expected should be clarified by
the respondents?
- Thank you for this comment. We have now clarified this point in the manuscript as ophthalmic surgery history included cataract surgery, refractive surgery, vitrectomy, glaucoma surgery, strabismus surgery, corneal transplants, orbital surgery, or retinal laser treatment, see lines 104-107.
- Once self-medication has been abbreviated as SM in the text, it should be used
everywhere in the text following.
- Thank you for this comment. We have now addressed this comment in the manuscript throughput the manuscript.
- Line 62 – OTC has not been defined previously.
- Thank you for this comment. We have now addressed this comment in the manuscript, see line 67.
- The aim of the study was to explore the prevalence and identify the predictors of
practicing SM, what was done after completing the study? This point is not critical,
but it may add scientific weightage to the study done.
- Thank you for this comment. This study has identified high risk population for SM practices and provided recommendations for future research. We have now highlighted these points in the manuscript and in the conclusion.
- Another point I would like to have explanation is that the study was done at a
specific center, dealing with diabetic patients. That means that population sample
which took part in the study were from a specific group. But the sample size was
calculated from the total population of Jordon. Pl. specify.
- Thank you for this comment. We have now addressed this comment and recalculated the sample size for patients with diabetes in Jordan. The National Centre for Diabetes, Endocrinology, and Genetics (NCDEG) in Amman, Jordan is the largest centre for diabetes management in Jordan. Patients from all over the country refer to this centre. The number of annual visits for this centre exceed 500,000 visits every year. Based on the International diabetes Federation, the estimated number of Jordanians with diabetes mellitus is around 866,500 individuals, therefore, with a confidence interval of 95%, a standard deviation of 0.5, and a margin of error of 5%, the minimum required sample size was 379 patients, see lines 131-137.
- Line 85- pl. start the sentence with capital letter.
- Thank you for this comment. We have now addressed this comment, see line 101.
10.Paragraph (line 120-127), pl. check English, some meanings are not clear.
- Thank you for this comment. We have now addressed this comment.
11.Table 1 –
- the age groups defined in the table differ from each other: 18-23 years – 5
years; 24-30 years – 6 years; 31-35 years – 4 years and so on. Pl. make
changes accordingly.
- Thank you for this comment. We have now addressed this comment, see Table 1.
- What difference do authors meant when they described “bachelor’s degree
and higher education” etc. pl. clarify.
- Thank you for this comment. We have now clarified that higher education means (Master degree and PhD), see Table 1.
- c. The authors should retabulate the data of table 1. Specify the comorbidities
as per the international classification of diseases. That will be more
presentable.
- Thank you for this comment. We have now addressed this comment, see Table 1.
12.Figure 1. The percentage values have been given twice in the same graph. Pl. check.
- Thank you for this comment. We have now addressed this comment and replaced the figure, see Figure 1.
13.Line 156 -meaning not clear.
- Thank you for this comment. We have now addressed this comment and clarified the sentence.
14.Lines – 171-178. The authors compare their results with results of similar type of
studies from other countries. The comparison in my opinion is not suitable, the
authors studied specific group of patients from diabetic clinic, where the mentioned
studies dealt with other types of groups e.g. reference 5-7 and others.
- Thank you for this comment. In light of the absence of any prior research that investigated self-medication among diabetic patients with ophthalmic conditions, we preferred to compare our results with those of comparable studies that have addressed self-medication in other patient populations. This approach was implemented to emphasize the novelty of our research by concentrating on this particular subgroup and to provide context. Besides, based on the reviewer comment, we have now added this point to the study limitations, see lines 373-376.
15.Very detailed discussion – this can be reduced in size to make it more appropriate.
- Thank you for this comment. We have now addressed this comment as appropriate.
16.Line 242 – pl. check the English.
- Thank you for this comment. We have now addressed this comment, see page 10.
17.In conclusion – pl. specify the findings/results as per the aim/aims of the study.
- Thank you for this comment. We have now addressed this comment and revised the conclusion.
Overall, the manuscript needs major revision.
Thank you for your valuable comments. We have now addressed all comments as highlighted in the manuscript.
Reviewer 2 Report
Comments and Suggestions for AuthorsThe manuscript, "Self-Medication Among Patients with Ophthalmic Conditions in Jordan: A Cross-Sectional Study," performs a study on a very important topic for the safety of medicines.
Title - Options for Improvement
The title is an important issue in an article and is the “face” of the research. For that reason, look for the two options and reasoning,
1. Highlighting the Core Findings
o "Prevalence and Predictors of Self-Medication Among Ophthalmic Patients in Jordan: A Cross-Sectional Analysis"
2. Emphasizing the Risks and Context
o "Self-Medication Practices and Associated Risks Among Ophthalmic Patients in Jordan: A Cross-Sectional Study"
Limitations
1. Introduction
o Regarding the type of sample there is a lack of information about patient's engagement with pharmacovigilance and adverse drug reactions.
2. Study Design and Generalizability
o The study is limited to a single health center, which restricts the generalizability of the findings to the broader population in Jordan or similar settings.
o The cross-sectional design does not allow for causal inferences or long-term insights into the effects of self-medication practices.
3. Data Collection Bias
o The reliance on self-reported data through questionnaires may introduce social desirability bias, where participants could provide responses perceived as socially acceptable rather than truthful.
4. Sample Representation
o While the sample size exceeds the minimum requirement, the overrepresentation of older individuals (51 years and above) may skew the findings, as this age group may differ significantly in self-medication behaviours compared to younger cohorts.
5. Lack of Comparative Context
o The manuscript mentions prevalence rates from other countries but does not delve deeply into why these differences exist or how they inform the findings in Jordan.
6. Discussion of Risks
o Although risks of self-medication are highlighted, there is limited emphasis on specific interventions or strategies to mitigate these risks, such as public health campaigns or regulatory changes.
7. Visual Data Representation
o Figures and tables are underutilized for summarizing key findings, such as the predictors of self-medication or side effects.
8. Ethical Considerations
o While ethical approval is mentioned, there is no detailed discussion of how participant confidentiality and data security were ensured. Also, state if the consent was informed.
Recommendations for Improvement
- Introduction
o Consider the introduction of the topic of patients' engagement with ADR and risk perception increasing also the broad of references. If you agree look for the following suggestions.
· Joaquim, J.J., Matos, C., Mateos-Campos, R. Assessment of risk perception of patients concerning adverse drug reactions. Curr. Issues Pharm. Med. Sci., 2023, 36(2), pp. 103–107. https://doi.org/10.2478/cipms-2023-0018

- Expand Generalizability
o Consider including multiple centers or regions in future studies to enhance the representativeness of the findings.
- Mitigate Bias
o Employ strategies to minimize social desirability bias, such as anonymous surveys or validated instruments.
- Broaden Age Representation
o Ensure a more balanced age distribution to explore age-related trends in self-medication practices comprehensively.
- Enhance Comparative Analysis
o Provide deeper analysis comparing Jordanian practices with those in other countries, focusing on cultural, regulatory, and healthcare system differences.
- Propose Interventions
o Suggest concrete measures, such as pharmacist training or stricter regulation of OTC drugs, to address the identified issues.
- Improve Data Visualization
o Include additional charts or graphs to make complex data more accessible, such as a heatmap for predictors of self-medication or a flowchart of common self-medication pathways.
- Ethical Transparency
o Expand on the ethical safeguards implemented during the study, such as data anonymisation and informed consent processes.
Some questions to clarify some topics
Study Design and Methodology
1. Generalizability
o How do you plan to address the limited generalizability of the findings due to the single-center study design? Would you consider including multiple centers in future studies?
2. Bias Mitigation
o What measures were taken to reduce social desirability bias in participants’ responses to the self-administered questionnaire?
3. Sampling
o Given the overrepresentation of older participants, how might this affect the applicability of your findings to younger populations? Could you explore age-stratified analyses?
Data Presentation
4. Visual Representation
o Could you include additional figures or tables to summarize key findings, such as predictors of self-medication or the prevalence of specific symptoms leading to self-medication?
5. Comparative Context
o Can you provide a more detailed comparison of your findings with similar studies in other regions or countries? What cultural or systemic factors might explain the differences?
Discussion and Interpretation
6. Intervention Strategies
o Could you propose specific public health interventions or policy recommendations to address the risks associated with self-medication in Jordan?
7. Risks and Benefits
o While the risks of self-medication are discussed, could you elaborate on the potential benefits and how they can be maximized through proper education or regulation?
Ethical Considerations
8. Participant Confidentiality
o How was participant confidentiality ensured during data collection and analysis? Were any additional safeguards implemented?
9. Consent Process
o Could you elaborate on how informed consent was obtained, particularly for participants with limited literacy or understanding of the study’s purpose?
Limitations and Future Directions
10. Study Limitations
o The study mentions the cross-sectional design as a limitation. Could you suggest alternative study designs that might provide more robust insights, such as longitudinal studies?
11. Future Research
o What additional research questions have emerged from your findings, and how do you plan to address them in subsequent studies?
Context and Relevance
- Cultural Factors
o Could you discuss in greater detail how cultural attitudes towards healthcare and self-treatment in Jordan might influence self-medication practices?
- Healthcare System
o How do you think gaps in the healthcare system, such as accessibility or cost, contribute to self-medication trends? Could these be mitigated through systemic changes?
Overstated Claims and Suggestions
1. Claim
o "Self-medication, especially in the field of eye diseases, is considered a double-edged sword that may be harmful but could also have benefits, provided that it is practiced correctly."
Issue This statement implies that self-medication can be beneficial if done correctly, but the study does not sufficiently explore or provide evidence for the "benefits" of self-medication.
Suggested Rephrase
o "Self-medication for eye diseases carries significant risks and requires careful consideration to avoid harmful consequences."
2. Claim
o "The prevalence of self-medication among patients with ophthalmic conditions in Jordan is lower compared to other countries, indicating better healthcare practices or stricter regulations."
Issue The study does not provide direct evidence linking the lower prevalence to healthcare practices or regulations.
Suggested Rephrase
o "The prevalence of self-medication among patients with ophthalmic conditions in Jordan is lower compared to some countries, which may reflect differences in healthcare accessibility, awareness, or cultural attitudes."
3. Claim
o "Patients who self-medicate with herbal products believe these treatments are risk-free and effective."
Issue The manuscript does not provide data on patients’ perceptions of herbal treatments being "risk-free."
Suggested Rephrase
o "Patients who self-medicate with herbal products may perceive these treatments as safer alternatives to pharmaceuticals, though this perception warrants further investigation."
4. Claim
o "The younger age group was more dependent on self-medication, governing the inverse relationship between age and self-medication."
Issue The term "governing" is too strong without clear evidence of causality.
Suggested Rephrase:
o "The younger age group exhibited higher rates of self-medication, suggesting a potential inverse relationship between age and self-medication practices."
5. Claim
o "The abundance of over-the-counter medications in Jordan makes it easy for patients to self-medicate for any disease at any time."
Issue The phrase "any disease at any time" is overly broad and not substantiated by the study.
Suggested Rephrase
o "The availability of over-the-counter medications in Jordan facilitates self-medication for various conditions, including ophthalmic diseases."
General Recommendations
· Use cautious language like "may," "suggests," or "could indicate" when discussing findings that are not directly supported by data.
· Avoid making causal claims unless the study design and analysis provide robust evidence.
· Ensure all statements are directly supported by the data or references cited in the manuscript.

Round 2
Reviewer 1 Report
Comments and Suggestions for AuthorsThanks for the revision!
The article has improved considerably.
The additional explanation needed is again for table 1. The age-groups: the first age group has been mentioned as 18-25 (7 yrs period), where other groups are having 4 years period. Pl. clarify! Or pl. explain at the foot of the table!
pl. also explain why authors have selected a difference of 4 years, not 5 years.
Author Response
Thank you for this comment. We have now justified this point in the footnote for Table 1 based on the reviewer comment.
