  1. Values shown are OR (95% CI). Cells with a dash indicate that the variable was not included in the model. Cells with two dashes indicate that the variable was included in the multivariate model but excluded after the multivariate 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; *P < 0.05; **P < 0.001; # P < 0.001. eGFR, estimated glomerular filtration rate (mL/min/1.73 m2); OR, odd ratio; CI, confidence interval
