*OR, odds ratio; CI, confidence interval; aOR, adjusted odds ratio. †OR adjusted for all variables that were significant in univariate analyses at p<0.05. ‡Prior reported antibacterial product use was controlled for but did not have any effect on the point estimate. Therefore, "group" point estimates reflect use of antibacterial product after randomization.
