Parasitological data of HbAA (green) and HbAS (orange) gametocyte carriers used for membrane feeding assays. A median gametocyte densities in HbAS, 72 parasites/µl [IQR 56–200], and in HbAA, 56 parasites/µl [IQR 32–132], were not different (Wilcoxon sum rank test = 1101, P = 0.292). B MOI of gametocyte stages in HbAS carriers was significantly lower than that in their HbAA counterparts, 2 [IQR 1–3] versus 3.5 [IQR 2–6] respectively (Wilcoxon sum rank test = 188, P = 0.032). Each dot represents data from a gametocyte donor
