Estimates are based on the predicted numbers anaemic in each risk group given by the mean and individual-level SD at each realisation of the Bayesian multivariate model for Hb, and are shown for two demographic groups by Province.
N/a, no children are exposed (ie, prevalence of predictor is zero in this demographic group).
*Exposure to ‘acute malnutrition’, prevalence of wasting in under 5s exceeds 5%.
