Effect of Uncertainty in Illness and Fatigue on Health-Related Quality of Life of Patients on Dialysis: A Cross-Sectional Correlation Study
Round 1
Reviewer 1 Report
This paper provides data useful for planning programs to advance physical and mental health among patients needing dialysis care. The quality of writing is fine. Although data were collected from a convenience sample, findings from the multivariable analysis can offer useful messages.
There is one mistake that the authors need to revise. Data in Table 4 shows that patients with higher education attainment had lower mental health related quality of life, but the authors reported these patients had better mental health. Please confirm which direction was correct. If patients with higher education attainment had worse mental health, please elaborate more about how to help this type of patients.
Please also elaborate more about how to advance mental health among patients who were not smoking, and also propose possible intervention programs to help smoking patients to quit smoking without hurting their mental health.

Reviewer 2 Report
Nice work with very interesting results. Hemodialysis patients who are older and longer dialysis vintage on hemodialysis for longer have a better quality of life and fewer complaints. Undeniably, more investigations are to be conducted on a larger group of patients and in different populations.
In my opinion introduction could be a bit shorter.
