Table 2: Travel activities associated with statistically significant change in odds of acquiring ESBL-producing Escherichia coli on multivariable analysis
Travel activityOR* (95% CI)
Visited India19.9 (4.5-88.8)
Consumed meals with local population6.9 (1.2-39.6)

Note: CI = confidence interval, ESBL = extended-spectrum β-lactamase, OR = odds ratio.

*Based on generalized linear mixed model fit by maximum likelihood; adaptive Gauss-Hermite quadrature (nAGQ) = 50, Bayesian information criterion = 127.6.
