a This table presents a measure of central tendency with its associated uncertainty bound from each study. Because studies differ in how they measure central tendency and uncertainty, we cannot label the columns with a single heading. Measures include: this study (median, 90% credibility interval (CI)); Havelaar et al. [40] (mean, 90% CI); Gkogka et al. [59](median, min-max); Ravel et al. [42] (mean, 95% CI); Scallan et al. [60] (mean, 90% CI); Lake et al. [41] (mean, 95% CI); Valley et al. [44] (median, 95% CI).
b These estimates were derived by a synthesis of data from different public health surveillance systems and the literature.
c Only ETEC cases reported as part of foodborne outbreaks were included in the study by Scallan et al. [60]. Consequently the proportion foodborne was per definition 100% and cannot be readily compared with the estimate in this study, which considers infections acquired from all transmission routes.
