Box plot showing genus-level microbial diversity of phages based on the independent cohort of humans treated with antibiotics. The microbial diversity was measured by diversity indices including the Shannon index (a), Simpson index (b), and Pielou eveness index (c). Data are shown based on three conditions before treatment, at the end of treatment and at 90 days after the end of treatment. The alpha diversity of before-treatment (“exposed 0”) phage communities was significantly higher compared to group exposed to antibiotics for 7 days (“exposed 7”) (Wilcoxon test; Shannon index, p < 0.044)
