Assessment for differences in salt disappearance by household size and National Wealth Equity Index quintile were evaluated using the Kruskal–Wallis test (with the Dunn–Bonferroni post‐hoc test; different superscript numbers in the same column indicate significant differences); differences by agricultural season were assessed using the Mann–Whitney U test.
Includes household members ≥2 years of age.
National Wealth Equity Index score is calculated using EquityTool, quintiles standardized to the 2014 Cambodian Demographic and Health Survey19 (https://www.equitytool.org/cambodia/).
Observation is defined as one fortnightly home visit.
