Effects of the Informed Health Choices primary school intervention on the ability of children in Uganda to assess the reliability of claims about treatment effects, 1-year follow-up: a cluster-randomised trial

Table 13 Self-reported behaviour: awareness of treatment claims

How often do you hear treatment claims?
	Control schools N = 2844	Intervention schools N = 3943
One or more most days	572 (20.1%)	1000 (25.4%)
One or more most weeks	374 (13.2%)	599 (15.2%)
One or more most months	497 (17.5%)	715 (18.1%)
Almost never	653 (23.0%)	788 (20.0%)
I don’t know	717 (25.2%)	810 (20.5%)
Missing	31 (1.1%)	31 (0.8%)
One or more most days or most weeks	946 (33.8%)	1599 (40.6%)
Odds ratio^a	1.35 (95% CI, 1.02–1.79) P = 0.0356
Adjusted difference^b	7.0% (95% CI, 0.5–12.9%)

^aThe odds ratio for the dichotomised data is shown in the table. The odds ratio from the mixed ordinal logistic regression was 1.30 (95% CI, 1.01 to 1.67; P = 0.0431)
^bThe difference is an adjusted difference, based on a mixed model with a random effects term for the clusters and the stratification variables modelled as fixed effects, using logistic regression. The odds ratio from the logistic regression has been converted to a difference using the intervention schools as the reference and the inverse of the odds ratios shown here
