Univariate and multivariate logistic regression analysis for eGFR(1 = eGFR≥60 mL/min/1.73 m2; 2 = eGFR2).

(Serum calcium is corrected by the following formula:[serum calcium] (mg/dL) = measured [serum calcium] (mg/dL)+(4.0−[serum albumin(mg/dl)]) × 0.8. Variables of univariate regression include age, sex, hemoglobin, serum calcium, phosphate and iPTH, all BP values from the clinic BP and ABPM, and reversed BP patterns, all variables with significant associations with eGFR were included in multivariate regression analysis. DBP: diastolic blood pressure; eGFR: estimated glomerular filtration rate; iPTH: intact parathyroid hormone, SBP: systolic blood pressure).
