Figure 1From: Sickle cell trait (HbAS) and stunting in children below two years of age in an area of high malaria transmissionRelationship between stunting and age in children with and without malaria episodes. Proportion of children stunted with increasing age stratified for b-globin genotypes HbAA (dots and solid line) and HbAS (crosses and dashed line). GEE analyses with adjustment for within-group, between-group effects and age-dependency were performed with autoregressive correlation structure of order 5 and assumption of binomial variable distribution. A, children without malaria episodes; no significant protective effect of HbAS (OR 0.84; CI 0.33–2.15; p = 0.71). B, children with at least one episode of malaria; 51% lower risk of stunting (OR 0.49; CI 0.25–0.93; p = 0.03).Back to article page
