GSTM1 and infection: In contrast, there was a significant effect of msp2 allelic diversity (F2,710 = 4.84, P = 0.008, Fig. 3c), with patients harboring parasite genotype msp2–3D7 in mono-infection showing higher level of Hb than mixed-infected individuals (3D7_FC27) (post-hoc multiple pairwise comparisons: 3D7 versus 3D7_FC27, t = 2.7, P = 0.02; 3D7 versus FC27, t = 1.7, P = 0.18; FC27 versus 3D7_FC27, t = 0.14, P = 0.98).
