Table 3 Prevalence and PR (95% CI) of having water and soap at handwashing place at 30 participating public primary schools in Kisumu County, Kenya, by pre-intervention vs. post-intervention status

From: Effect of an equipment-behavior change intervention on handwashing behavior among primary school children in Kenya: the Povu Poa school pilot study

Item Pre-intervention visits Post-intervention visits
Post-Intervention, all visits Post-Intervention Visit 1 (0–5 weeks after intervention) Post-Intervention Visit 2 (6–19 weeks after intervention) Post-Intervention Visit 3 (20–25 weeks after intervention)
