  1. Table of statistical tests between matched-pair healthy subject time intervals to determine the significance of measured differences in observed species counts. Species counts were calculated from samples rarefied to 75,000 reads. Testing for matched-pair healthy samples used one-tailed (alternative = “greater”) Wilcoxon signed rank.
  2. aNon-matched pair probabilities for groups with C. difficile (CD) were calculated using one-tailed (alternative = “greater”) Wilcoxon rank sum with continuity correction.
