aAtopy outcomes assessed by IgE were adjusted for age and sex only.
bFor this outcome, a natural log transformation was applied to village-level proportions to correct skewed distributions, and the data in parentheses are the geometric means of village proportions.
cLog10(+0.001) transformation at the individual level.
dLog10(+1) transformation at the individual level.
