Microbiome recovery from antibiotics. Recovery was assessed among participants reporting use of antibiotics during the two years of collection. Percent change in Shannon index (A) and phylogenetic diversity (B) was calculated relative to the baseline sample and categorized on time since last reported antibiotic use. Changes in alpha diversity for each time interval were assessed using a one-sample t-test for a mean of zero (*p<0.05). Distances from baseline were computed for unweighted UniFrac (C) and weighted UniFrac (D) measures. Comparison of six-month to baseline samples among participants not taking antibiotics are also included.
