Table 1. Correlation coefficients between REN and HF microbiota and SCC across all samples.

Pearson’s linear correlation coefficient was calculated between SCC and relative abundances of microbial taxa on the 117 samples. Only correlations with a p-value of the linear model < 0.01 are reported. For each significant correlation, the average relative abundances of the specific taxa in REN and HF are reported.
