*Statistically significant by using Chi-Square test, BPH (benign prostatatic hyperplasia), Hb (haemoglobin), TG (triglycerides), LDL (low-density lipoprotein), HDL (high-density lipoprotein), eGFR (estimated glomerular filtration rate), DBP (diastolic blood pressure), CKD (chronic kidney disease), and BUN (blood urea nitrogen). Here, GSTM1 is linked to chronic kidney disease.
