Results: The mean plasma KIM-1 level was 403.8 ± 546.8 pg/mL, showing a statistically significant correlation with inflammation (CRP, R = 0.28, p = 0.02; IL-6, R = 0.36, p = 0.005) and with anemia (hematocrit, R = −0.5, p = −0.0316; hemoglobin (Hb), R = −0.5, p = 0.02). Here, GSTM1 is linked to anemia.
