Distribution of rural household dietary selenium (Se) supplies and prevalence of inadequacies. Household dietary supplies are quantified per Adult Male Equivalent (AME). Prevalence of inadequate supplies are quantified as percent (%) of households with dietary Se supply less than sum of household member Estimated Average Requirements (EARs) and Reference Nutrient Intakes (RNIs); the EAR and RNI for an adult male are 45 and 55 μg d⁻¹ [41]. Households are aggregated by soil type (calcareous = dark grey, non-calcareous = white) and expenditure quintile (1 = poorest, 5 = wealthiest). Boxes are median, Q1 and Q3, notches estimate the median’s 95% confidence interval, whiskers extend 1.5x Q1 and Q3
