Difference in enteropathogen detection in the antibiotic versus placebo arms at 6, 6.5, 12, 12.5, and 18 months.
PENICILLINS
X axis is the absolute difference in pathogen prevalence between the antibiotic and placebo arms. Negative values to the left of 0.0 represent lower carriage in the active arm.Because children frequently received non-study antibiotics, we examined the effect of receiving such antibiotics on pathogens as well. Penicillins were the most frequently used class, followed by metronidazole, sulfonamides, and macrolides (
