  1. Values shown are OR (95% CI). Impaired HRQOL was defined as the lowest quartile of EQ-5D weighted values. Potential risk factors in the unadjusted analysis (P < 0.05) were included in the adjusted analysis. The multivariate logistic regression analysis model was derived using the backward conditional method. †Students, soldiers and housewives; ‡middle and high school graduates; §elementary school or no education. HRQOL, health-related quality of life; eGFR, estimated glomerular filtration rate (mL/min/1.73 m2); OR, odds ratio; CI; confidence interval
