Studies included in this review. (A) Flowchart showing the search strategies and the exclusion criteria used to locate the relevant studies in this review. (B) This panel lists the studies included in this synthesis and the outcomes (O1-O5) reported by each study. The outcomes are color-coded and the colors are consistently used in the rest of the paper. A colored square in the grid indicates that the specified outcome was reported by a trial while a blank square in the grid indicates that the outcome was not reported. The outcomes are as follows: O1, incidence of diarrhea; O2, prevalence of diarrhea; O3, incidence of persistent diarrhea; O4, incidence of dysentery; O5, mortality. Total number of studies and comparisons (when more than one zinc regimen was compared to the same reference group) are indicated at the bottom for each outcome.
