Outcome variable	Unadjusted	Adjusted
	OR (95% CI)	aOR* 95% CI
Ascaris lumbricoides prevalence	1·00 (0·61–1·34)	0·88 (0·57 to 1·34)
Trichuris trichiura prevalence	1·05 (0·60–1·83)	0·88 (0·62 to 1·25)
Hookworm prevalence	1·66 (0·95–2·89)	1·13 (0·51 to 2·50)
Any STH prevalence	1·10 (0·57–2·14)	1·00 (0·58 to 1·72)

^* Odds ratios adjusted for sex, SES status, age, running water in the home, time of year of baseline visit, length of follow-up, baseline parasitological prevalence, random effects at the school level, and fixed effect for the matched-pairs.
