Table 5. Effect of the health hygiene intervention on STH intensity (EPG†) at follow-up (four months post-deworming) in multivariable random effects negative binomial regression models.
Outcome variable | Unadjusted | Adjusted |
IRR (95% CI) | aIRRa 95% CI | |
Ascaris lumbricoides intensity (EPG†) | 0·52 (0·27–1·01) | 0·42 (0·21 to 0·85)* |
Trichuris trichiura intensity (EPG†) | 1·56 (0·98–2·48) | 1·14 (0·78 to 1·67) |
Hookworm intensity (EPG†) | 1·57 (0·28–8·81) | 0·11 (0·01 to 1·49) |
Incidence rate ratios (IRR) adjusted for sex, SES status, age, running water in the home, time of year of baseline visit, length of follow-up, baseline parasitological intensity (epg), random effects at the school level, and fixed effect for the matched-pairs.
EPG: eggs per gram.
Statistically significant effect measure.
