Excerpt from Abstract
"The intervention was associated with improvements in the prevalence of cleaning rotas (relative risk 1·16, 95% CI 1·05–1·30; p=0·0011), inside locks (1·34, 1·10–1·64; p=0·00081), outside locks (1·27, 1·06–1·52; p=0·0028), and toilets with simple covers or water seals (1·25, 1·04–1·50; p=0·0063)."
