The case group had significantly higher frequencies of M1, S1, T1 and T2 score (P < 0.05) and higher levels of sCr, UA, TC, 24 h urinary protein and the proportion of hypertension at biopsy than in control group (P <0.05), while Hb, Alb, eGFR and the proportion of hematuria history were lower than those in control group (P <0.05) (Table 1). Here, GSTM1 is linked to Hematuria.
