Impact of universal home visits on child health in Bauchi State, Nigeria: a stepped wedge cluster randomised controlled trial

Table 5 GEE modelling for intervention effect on management of diarrhoea and on intermediate outcomes in children aged 12–18 months in intervention and control groups

Outcomes	Proportion(n/N)		Robust OR (95% CI)
Outcomes	Intervention	Control	Modelled with intervention alone^a	Modelled with other characteristics^b
Primary outcomes^c
Given more fluids and continued feeding during last episode of diarrhoea	0.437 (118/270)	0.098 (147/1502)	6.06 (2.58–14.20)	6.06 (2.58–14.20)
Not given any medicine to stop diarrhoea during last episode of diarrhoea	0.489 (132/270)	0.074 (112/1511)	9.21 (3.71–22.89)	10.17 (3.87–26.76)
Intermediate outcomes
Mother thinks child with diarrhoea should be given more fluid and continued feeding	0.396 (700/1767)	0.114 (584/5105)	4.35 (2.53–7.50)	4.35 (2.53–7.50)
Mother would not give a child medicines to stop diarrhoea	0.366 (647/1767)	0.031 (157/5105)	12.53 (5.82–26.96)	75.11 (6.24–903.18)

OR Odds Ratio, 95% CI 95% confidence interval; Bold font indicates a difference significant at the 5% level
^a The GEE model for each outcome included only the intervention with ward as cluster
^b The GEE initial saturated model for each outcome included the intervention with other variables potentially related to the outcome shown in Table 3, as well as ward as cluster. The variables remaining in the final model for each outcome are shown in Additional file 3. For all outcomes, the intervention variable remained in the final model. For some outcomes no other variable remained in the final model
