Wilcoxon signed rank test on the eight most abundant phyla (A) and families (B) in fecal samples collected after two nights (d2) of either partial sleep deprivation (PSD) or normal sleep (NS). Percent relative abundance means are shown and values are shown as mean ± SD. One-sided P values are shown (significance is displayed in bold font). V, Wilcoxon test statistic value.
