CI confidence interval
ap ≤ 0.05 means observed differences between comparison groups is statistically significant or not significant if p > 0.05
bRisk ratios were modelled using binomial regression. Treatment group, age category, baseline parasitaemia and mild anaemia, and gravidity were included in the final model
