Forest plots of the effects of WS conditions on malaria infection among the total children diagnosed by microscopy. The ORs and 95% CIs for the risk of infection as determined by microscopy in relation to (A) Unprotected Water, (B) Piped Water, (C) No Facility, and (D) Flush toilets in each survey were measured by logistic regression models with adjustments for age, gender, IRS, ITN use, house quality, and mother’s highest educational level. The datapoints, lines, boxes, and vertical dashed lines present the ORs, 95% CIs, weight that each survey contributed to the overall OR, and overall 95% CIs, respectively. WS = Drinking Water and Sanitation; OR = Odds Ratio; 95% CI = 95% Confidence Interval.
