Multivariate Logistic Analysis of Predictors for Frailty

Variables	Adjusted OR*	95% CI	P-value
Age (per 1 year increase)	1.393	1.241–1.563	<0.001
Gender (female)	1.920	1.014–3.636	0.045
History of diabetes	3.610	1.262–10.327	0.017
Dialysis vintage (per 1-month increase)	1.011	1.002–1.020	0.019
Single-pool Kt/V (per 0.1 increase)	0.711	0.516–0.979	0.037
ALB (per 1g/L increase)	0.754	0.644–0.882	<0.001
iPTH (per 100pg/mL increase)	1.344	1.024–1.763	0.033

Note: All covariates with a P value of less than 0.10 on univariable analysis were entered into the multivariable model, including age, gender, marital status, history of diabetes, dialysis vintage, single-pool Kt/V, and the levels of albumin and iPTH.

Abbreviations: OR, odds ratio; CI, confidence interval; Kt/V, an indicator for evaluating dialysis adequacy; ALB, albumin; iPTH, intact parathyroid hormone.
