Anna N Chard e outros, 2019 · Journal of Global Health
A comprehensive school-based WASH intervention in rural Lao PDR showed no detectable effect on pupil absence (aRR = 1.01, 95% CI: 0.84 to 1.20).

Contexto
What changed: Schools received water supply infrastructure, sex-separated toilets, handwashing stations, drinking water filters, and hygiene behavior promotion. Comparison: Control schools lacking functional WASH facilities during the study period. Limits: Intervention fidelity and adherence were low (around 30%), and student absenteeism was primarily driven by seasonal agricultural labor rather than illness.
