Round 1

Reviewer 1 Report

The authors produced an interesting work about factors of functional independence and quality of life of patients one month after a stroke. Despite the small sample size as stated on limitation section by the author they analysed a lot of different variable. This is surely a strenght of the manuscript which could interest the health professionals.

 

Comments for the authors

-) ‘’The sample consisted of 81 people who had previously suffered a stroke’’ (line 88)

This sentence is related to the result. In this section you have to specify inclusion/exclusion criteria, where do you select the group and if you stated or not a sample size and why do you state it. Improve a little bit this section.

-) On line 144 of the procedure you stated ‘’A randomized controlled….’’ why do you randomize the patient? this is a cross-sectional study so you do not need it. Explain

-) on table one the MIN/MAX value is not necessary

-) on table 2 could be interesting to add the numerosity for each subsample that you analysed.

This sentence is related to the result. In this section you have to specify inclusion/exclusion criteria, where do you select the group and if you stated or not a sample size and why do you state it. Improve a little bit this section.

Response: Thank you for your comment. Inclusion and exclusion criteria have been included.

 “This cross-sectional study was conducted in Burgos and Córdoba (Spain). The sample consisted of 81 people who had previously suffered a stroke. As inclusion criteria, it is contemplated that the participants are older than 18 years, with a diagnosis of residual hemiparesis due to stroke, those whose movement of the affected upper limbs is classified between stages II and IV of the Brunnstrom Scale [21].

The study population was recruited at discharge from the Neurology Service and Stroke Unit of both hospitals through consecutive sampling.”

 

-) On line 144 of the procedure you stated ‘’A randomized controlled….’’ why do you randomize the patient? this is a cross-sectional study so you do not need it. Explain

Response: Randomised control was performed for subsequent phases of the study. This information has been removed to avoid confusion in this manuscript.

-) on table one the MIN/MAX value is not necessary

Response: Se han eliminado las columnas en las que se recogían estos valores.

 

-) on table 2 could be interesting to add the numerosity for each subsample that you analysed.

Response: This information is given as descriptive information in the first part of the results.

 

We hope we have now answered all your comments and we are looking forward to hearing from you again.

 

Thank you very much,

Reviewer 2 Report

Thank you for the opportunity to review this interesting paper. Evaluating factors that most influence lives of people with stroke is certainly an interesting topic that can offer insights for health care and rehabilitation. 

Intro: I appreciated global data and specific focus on Spain context, also referring to ICF.

Methods:

INstruments: Please divide paragraph in quantiative and qualitative data. First describe qualitative apporach, then quantiative approach and please separate instruments sub-section dividing each outcome measure. This can help readers to follow your manuscript.

Procedures: who administered the outcome measures? Why you need a blind randomized sample in a cross-sectional study? Please clarify

Data analysis: considering you analyzed different variables, why you choose to perform only anova analysis, not also MANOVA? This can help to better understand how these variables can affect QoL in people with stroke.

Reviewer 3 Report

Dear Authors, 

 

Thank you for the opportunity to revise your manuscript. While the topic is relevant, there are serious concerns about the rational, study design, statistics and conclusions.

 

Please find below major issues:

 

-       In a cross-sectional study is not possible to draw casual relations between variables and outcomes. It is a correlation, that does not mean that a variable causes a change in the outcome. A controlled prospective study is needed. 

-       How the variables were selected?

-       Regression models should have been used. Correlations and mean differences does not answer to the research question. 

-       Confounding factors  should be considered

-       Post-hoc Bonferroni corrections should have been used. 

-       Sample size computation and power analysis is not presented. 

-       Inclusion and Exclusion criteria of participants are missing. 

-       No information is provided about the therapeutic intervention during the hospital stay of the patients. 

-       Methods are confusing, Authors should follow the STROBE guidelines

-       Conclusions overestimates the results. 

 

Consider that the topic was studied earlier: 

-Ones K, Yilmaz E, Cetinkaya B, Caglar N. Quality of life for patients poststroke and the factors affecting it. J Stroke Cerebrovasc Dis. 2005 Nov-Dec;14(6):261-6. doi: 10.1016/j.jstrokecerebrovasdis.2005.07.003. PMID: 17904035.

Dear Authors,

Thank you for the opportunity to revise your manuscript. While the topic is relevant, there are serious concerns about the rational, study design, statistics and conclusions.

Please find below major issues:

 

-       In a cross-sectional study is not possible to draw casual relations between variables and outcomes. It is a correlation, that does not mean that a variable causes a change in the outcome. A controlled prospective study is needed.  

Response: Thank you for your comment. In this cross-sectional study, the ANOVA test was used to compare the means of two or more groups and to identify whether they are significantly different. In this way, we can find out whether belonging to one group or another has a significant influence on the variables of interest.

 

-       How the variables were selected?

Response: Thank you for your comment. The variables used in the study were collected using a form that included both socio-demographic data and a battery of various scales measuring functionality, cognitive impairment and quality of life. These were therefore the variables taken into account in the study.

 

-       Regression models should have been used. Correlations and mean differences does not answer to the research question.

Response: The objective of the research has been changed to the following: “the main objective of this research is to study which factors are related to functional capacity and QoL a month after suffering a stroke, so that these can be considered in early interventions”.

-       Post-hoc Bonferroni corrections should have been used.

Response: This information has been added to the manuscript (see lines 223-225 and 268-269).

 

-       Confounding factors should be considered

Response: This information has been added to the manuscript (see lines 390-391).

 

-       Sample size computation and power analysis is not presented.

Response: This information has been added to the manuscript (see lines 96-101).

 

-       Inclusion and Exclusion criteria of participants are missing.

Response: Inclusion and exclusion criteria have been included:

“This cross-sectional study was conducted in Burgos and Córdoba (Spain). The sample consisted of 81 people who had previously suffered a stroke. As inclusion criteria, it is contemplated that the participants are older than 18 years, with a diagnosis of residual hemiparesis due to stroke, those whose movement of the affected upper limbs is classified between stages II and IV of the Brunnstrom Scale [21].

The study population was recruited at discharge from the Neurology Service and Stroke Unit of both hospitals through consecutive sampling.”

 

-       No information is provided about the therapeutic intervention during the hospital stay of the patients.

Response: The hospital intervention was carried out in the second phase, which resulted in a longitudinal study. Therefore, in this manuscript, it is not considered relevant to explain the intervention performed, the aim of which is not to test the effects of the intervention. 

 

-       Methods are confusing, Authors should follow the STROBE guidelines

Response: Thank you for your comment. For the presentation of the methods, the guidelines provided by the journal have been followed.

 

-       Conclusions overestimates the results.

Response: The conclusion has been modified to meet the objective.

 

 

Consider that the topic was studied earlier:

Response: Thank you for your comment. Following your suggestion, a MANOVA test was carried out to estimate the differences between the means of the categorical variables, by means of the joint comparison of the dependent variables (FIMFAM and NEWSQOL), but it was finally decided not to include it in the manuscript as the assumption of homogeneity of covariance matrices was not met (F=1.99; p<0.05).

 

 

 

We hope we have now answered all your comments and we are looking forward to hearing from you again.
