Table 2.
The incidence rate of strain carrying genes of EAEC infection across each of the eight study sites (Bangladesh, India, Nepal, Pakistan, South Africa, Tanzania, Brazil, and Peru) from November 2009 to February 2012.

95% CI: 95% confidence interval; Incidence rates were calculated using Poisson regression where outcome variables were a number of infections of EAEC ( strain carrying genes) and offset variables were log of the number of follow up.
