Prevalence in the blood group genotypes in population studied are presented as n (percentage, %). Data shown are number (n) and proportions (%) of study participants. Odds ratios (OR) and 95% confidence intervals (95% CI) were determined using multivariate logistic regression controlling for age and sex. SMA, severe malaria anaemia. A, blood group A.
