In our study, we present a comparative analysis of NLR and CRP in light of anemia, which revealed that despite the fact that CRP is significantly elevated in anemics, it was a less sensitive marker of Hb status compared to NLR, suggesting that the overall performance of the latter is superior to CRP in discriminating anemics from non-anemics. Here, GSTM1 is linked to anemia (phenotype).
