Table 1. Effects of seven binary clinical factors on the α- and β-diversity of patient skin and bedrail bacterial communities.

(A) PERMANOVA analyses of the effects of clinical metadata on observed β-diversity. Each test was based on the weighted UniFrac distance between samples, and significance was assessed through 105 permutations of the randomized data set. (B) Effects of clinical metadata on the α-diversity of skin and bedrail bacterial communities, based on Faith’s phylogenetic diversity index. Significance was assessed through a two-sided nonparametric t test with 105 permutations. For both (A) and (B), significant test results are highlighted in bold, and those that are significant after a Bonferroni correction for multiple comparisons are indicated with an asterisk.
