Taxonomic comparison for 3 main bacterial taxa between frozen and RT samples
Taxon F* RT3h* RT24h* RT2w* p value F vs RT3h p value F vs RT24h p value F vs RT2w
Bacteroides;uncultured bacterium 19 20 19 13 0.749 0.749 0.0349
Prevotellaceae;uncultured;human gut metagenome 7 6 5 3 0.6804 0.3189 0.0140
Bifidobacterium;uncultured bacterium 2 2 3 7 1 0.3964 0.0030

Statistical analysis was performed using Poisson regression model. * Values are mean proportion of sequences (%). p-value < 0.05 is considered significant; n = 4 subjects; F = frozen; UF1h = unfrozen during 1 h; UF3h = unfrozen during 3 h; RT = room temperature; 2w = 2 weeks; Taxonomy is indicated at the genus level and if not possible at the family level.
