However, patients receiving VCAs had significantly lower Hb levels (mean 94.9 ± 16.7 g/L, p < 0.001), higher inflammatory markers such as leukocytes (mean 19.6 ± 11.95 g/L, p = 0.005), and CRP (mean 195.0 ± 101.2 mg/L, p < 0.001), and higher kidney failure markers such as creatinine (mean 181.2 ± 120.1 μmol/L, p = 0.012) and BUN (mean 18.87 ± 15.7 mmol/L, p < 0.036). Here, GSTM1 is linked to kidney failure.
