GSTM1 and anemia: Similarly, those with malarial anaemia had lower weight (15.0 years [12.1–19.4] vs. 19.5 years [14.4–26.0], p = 0.032), RBC count (4.0 × 109/L [3.1–4.4] vs. 4.9 × 109/L [4.5–5.3], p = 0.001), Hb concentration (9.5 g/dL [7.9–10.4] vs. 12.6 g/dL [11.9–13.2], p = 0.001), haematocrit (28.5% [25.0–30.3] vs. 36.6% [34.8–39.5], p = 0.001), MCV (73.5 fL [69.1–6.7] vs. 78.6 fL [73.7–81.5], p = 0.013) and MPV (9.9 [9.5–10.1] vs. 10.1 [9.7–10.6], p = 0.040) compared to those with malaria without anaemia.
