PNPLA2 and hyperlipidemia: Positive correlations were found between serum ATGL levels and estimated glomerular filtration rates (eGFR), while negative correlations were observed with diabetes duration, hypertension history, hyperlipidemia, urine ACR (UACR), 24-h urine total protein (UTP), serum creatinine (SCr), blood urea nitrogen, uric acid, TNFR-1, and KIM-1/creatinine (KIM-1/Cr) levels (p < 0.05).
