An association with marginal significance between goitre grades and salt iodization across schools was observed: goitre grade 2 was observed less frequently in children with an adequately iodised salt sample from their household (15.5%; 95% CI = 10.7%-21.3%) when compared to children with a non-iodised salt sample from their household (20.6%, 95% CI = 15.2%-27.0%; Pearson’s χ 2 (4) = 9.585, P = 0.048).
