  1. n/N number of infections/at-risk population, aOR adjusted odds ratio, CI confidence interval, NS did not meet threshold on univariate analysis (P < 0.2) to be included in multivariate analysis. Based on rapid diagnostic tests (trace readings considered positive) in determining schistosomiasis, Bold statistically significant (P < 0.05)
