P-values Calculated by the P-Test from Comparisons of the Bacterial Community Found in Stool Samples Immediately (IM), after 12h, 24h 48h and 72h prior to DNA Extraction and Amplification of the16S rRNA

	Subject A	Subject B	Subject C	Subject D
p-values
IM x 12h	0.79	0.23	0.99	0.99
IM x 24h	0.99	0.01	0.90	0.72
IM x 48h	0.10	≤ 0.01	0.09	0.33
IM x 72h	0.19	≤ 0.01	0.08	0.59

P-values have been corrected for multiple comparisons using the Bonferroni correction. (Each p-value was multiplied by the number of pairwise comparisons performed). For each pairwise comparison, if the p-value is less than or equal to 0.001 the result indicates a highly significant difference in the composition of the communities sampled by each library. P-values from 0.001 to 0.01 indicate a significant difference, from 0.01 to 0.05 indicate a marginally significant difference, from 0.05 to 0.1 indicate a suggestive difference and if the p-values are greater than 0.1 the result indicate that the difference is not significant.
