Notes: CI = confidence interval.
aAll models are adjusted for age, sex, and education.
bAdjusted odds ratios for ordinal outcomes are estimated using ordinal logistic regression.
cAdjusted means for count outcomes are estimated using negative binomial regression.
dAdjusted means for continuous outcomes are estimated using generalized linear regression.
eHigher values of all outcomes indicates poorer health. All differences are calculated as Intervention mean − Control mean, negative scores indicate lower scores among the Intervention group.
