Univariate and Multivariate Cox Models for the Effects of Lower Extremity Muscle Strength on Survivala

  • a Analyses were performed using a Cox proportional hazards regression model. HR=hazard ratio, 95% CI=95% confidence interval.

  • b Unadjusted by clinicopathological factors of survival.

  • c Adjusted by age, sex, body mass index, time on hemodialysis, comorbidity score, and levels of serum albumin and C-reactive protein.

  • d Adjusted by applying a propensity score, which is a conditional probability of knee extensor strength determined by other clinicopathological factors.
