Association between STH infection and cognitive ability, nutritional indicators, school absence and performance (infected with any of the 3 types of STHs).

<p>Notes:</p><p>^a Estimated with multivariate regressions adjusted for student characteristics (gender, age, boarding status, ethnicity); student eating and sanitation habits (ever eats uncooked meat / vegetables, ever drinks unboiled water); as well as household and family characteristics (household size, number of siblings, pieces of durable assets, parental migrant status, parental education). Standard errors are adjusted for clustering at the township level.
