  1. Data are presented as proportions [n, (%)] of IL7 genotypes (72194 T/C and − 2440A/G) and haplotypes (TA, TG, CA, and CG). UM [uncomplicated malaria, non-severe malarial anemia (Hb ≥5.0 g/dL)] and SMA [severe malarial anemia (Hb < 5.0 g/dL)]; both with any density parasitemia. Non-carriers (0) and carriers (1). Statistical significance was determined by Chi-square analysis comparing UM versus SMA
