For each variable, the % is calculated on the effective number of patients for whom information was available.
The coefficient stands for the regression coefficient β between renal function and each independent variable; bincluding two patients with iUCD and 25 with decreased eGFR; cvalues are expressed as mean ± SD; dincluding three patients with cystic kidney dysplasia. **P-value ≤0.01; ***P-value ≤0.001.
CKD, chronic kidney disease; NRF, normal renal function.
