Prevalence of Depression and Its Associated Factors Among Hemodialysis Patients in Hodeida City, Yemen [Letter]

Prevalence of Depression and Its Associated Factors Among Hemodialysis Patients in Hodeida City, Yemen" by Alkubati SA et al. 1 It is a valuable and interesting research.The strengths of this study are as follows: (1) This study is the first to identify the prevalence of depression and its associated factors among Yemeni hemodialysis (HD) patients who are facing multiple war-related crises or ongoing political conflict and have been overlooked, remain undiagnosed and receive limited care.Paying more attention to the mental health of HD patients in developing countries or regions (eg, Yemen) and providing tailored psychological support and nursing care are the mission of healthcare professionals; (2) The study employed the OpenEpi website formula to calculate the sample size, which provided a new insight into the sample size estimation methods; 2 (3) The authors conducted in-depth discussion, fully compared their research findings with previous studies performed in other countries (eg, China, Jordan, Saudi Arabia, Lebanon, Malaysia, Palestine, etc), and analyzed the specific reasons for these differences.Nevertheless, this study encountered certain constraints and some areas for improvement: (1) The authors may consider using G*Power version 3.1.9.7 software 3 to calculate the sample size, a very quick and convenient software; (2) There are two areas in the text that need to be corrected: (a) Page 694, the Sex variable in Table 2 has incorrect N value for female.After correction, as shown in Table 1 of this letter.(b) Page 693, the description of "The results showed that only female (odds ratio (OR)=0.298;95% confidence interval (CI)=0.132-0.674;p=0.004)" is inconsistent with the results in Table 3 of page 695, it should be described as "The results showed that only female (odds ratio (OR)=3.352;95% confidence interval (CI) = 1.484-7.570;p=0.004)"; (3) The variables included for binary logistic regression analysis in this study are relatively limited.Some professionally significant factors related to depression were not included in
