|Taxonomic comparison for 3 main bacterial taxa between frozen and unfrozen samples|
|Taxon||F*||UF1h*||UF3h*||p value F vs UF1h||p value F vs UF3h|
|Prevotellaceae;uncultured;human gut metagenome||7||6||3||0.6804||0.0222|
Statistical analysis was performed using Poisson regression model; p value < 0.05 is considered significant; n = 4 subjects; * Values are mean proportion of sequences (%).
F = frozen; UF1h = unfrozen during 1 h; UF3h = unfrozen during 3 h; Taxonomy is indicated at the genus level and if not possible at the family level.
