Table 2 Comparison of pathogen prevalence between prior review and update

From: Travelers’ diarrhea: update on the incidence, etiology and risk in military and similar populations – 1990-2005 versus 2005–2015, does a decade make a difference?

  1. The prevalence of specific bacterial pathogens identified by testing. Prevalence was compared between the prior systematic review and studies performed since that time (2006–2015). The number of studies in each subgroup (n) is included. Comparison of median values between groups was analyzed using Wilcoxon signed-rank testing
