In uncomplicated malaria control cases, 313 HbAA, 62 HbAC, 6 HbCC, and 10 HbAS cases were examined for splenomegaly. In the severe malaria cases, 61 HbAA, 3 HbAC, 0 HbCC, and 3 HbAS cases were examined for splenomegaly. The prevalence of splenomegaly was significantly more frequent in patients with severe malaria than in uncomplicated malaria controls (chi-square test, P<.001; OR 2.73; 95% CL, 1.54-5.31).
