Table 3: 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
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.
