The model included below- and above-median-eGFR categories (97 mL/min/1.73 m2 for females, and 103 mL/min/1.73 m2 for males) as a binary dependent variable, and log-transformed uPTM3-FetA, adiponectin, leptin, resistin, HDL-cholesterol, hs-CRP, WBC, AER, eGDR, HbA1c and diabetes duration, respectively, as continuous independent variables (Table 2), with sex as a biological confounder. Here, RETN is linked to diabetes mellitus.
