Multivariate linear regression analysis between PHQ-9 score and NLR

Item	Model 1		Model 2
	β (95% CI)	P	β (95% CI)	P
NLR	0.252 (0.194–0.803)	0.001	0.246 (0.175–0.799)	0.002
Alb	− 0.145 (− 0.364–0.011)	0.065	− 0.159 (− 0.397–0.008)	0.059

^*Significant at p < 0.05

Model 1: unadjusted

Model 2: adjusted for age, sex, Kt/V, dialysis duration, history of kidney transplantation, history of hypertension, and Charlson comorbidity index score
