Extended Data Fig. 2: Detection of VE303 Strains in All Participants Over Time.

Stacked-bar charts showing detection of individual VE303 strains over time, presented for each participant by treatment group: A, VE303 high-dose, B, VE303 low-dose, and C, placebo. Data are shown for all analyzed samples. D, Exposure to individual VE303 strains after screening and through Day 28. The mean relative abundance per participant over the indicated period is shown across the three treatment groups; VE303 high-dose n = 26; VE303 low-dose n = 26; placebo n = 20. The box-and-whisker plots depict the median, inter-quartile range [IQR] (at the top and bottom of the boxes), and reasonable extreme values at 1.5x IQR in the dataset.
