Parasitaemic children (n = 544) were categorized according to the WHO SMA definition [i.e., Hb<5.0 g/dL, with any density parasitaemia [26]] and the age- and geographically-appropriate definition of SMA [(Hb<6.0 g/dL, with any density parasitaemia [4]]. Odds Ratio (OR) and 95% confidence interval (CI) were determined using multivariate logistic regression controlling for age, gender, HIV-1, bacteremia, and sickle-cell trait (HbAS) status.
