Categorical data were analyzed using the chi-square test and continuous variables were analyzed using the Mann-Whitney U-test. Data represent median (IQR) or number (percentage). Group I: eGFR ≥60 mL/min/1.73 m², Group II: eGFR <60 mL/min/1.73 m². DM, diabetes mellitus; HTN, hypertension; eGFR, estimated glomerular filtration rate.
