Forest plots of relative risks of (a) viral and protozoan and (b) bacterial pathogens in community water sources in Sanitation Trial intervention over control villages. Relative risks for adenovirus in public tubewells and ponds were not calculated due to the small number of detected sources (n = 2 and n = 3, respectively). Relative risks for pathogenic E. coli in public and private tubewells individually, and combined (i.e. improved water sources) were not calculated due to the small number of detected sources (n = 1). V. cholera was not detected in open ponds.
