Nutritional and health status of children 15 months after integrated school garden, nutrition, and water, sanitation and hygiene interventions: a cluster-randomised controlled trial in Nepal

Table 6 Intestinal parasitic infections change during follow-up across the different study arms in Dolakha and Ramechhap districts, Nepal (March-May 2015 versus June 2016)

Outcomes	End-line (June 2016)			Effect of SG-intervention (95% CI)^b	p-value	Effect of combined intervention (SG+) (95% CI)^b	p-value
Outcomes	Control (n = 151/118)^a (%)	SG-intervention (n = 109/55)^a (%)	Combined intervention (SG+) (n = 120/71)^a (%)	Effect of SG-intervention (95% CI)^b	p-value	Effect of combined intervention (SG+) (95% CI)^b	p-value

Persistence was analysed in the sample of children who had the outcome at baseline and incidence among children who were free of the outcome at baseline
SG School garden
SG+ School garden, nutrition, and water, sanitation and hygiene (WASH)
^aThe first number (n) is for the children having been without the parasite at baseline and the second one (n) for children having been infected by the respective parasite at baseline
^bOdds ratio from a mixed logistic regression model of the outcome at follow-up as a function of the outcome at baseline and type of intervention, with random intercepts for the schools and further adjustment for the district, age and sex of the child, and socioeconomic status of the caregivers
