From: Storage conditions of intestinal microbiota matter in metagenomic analysis

Taxon F* RT3h* RT24h* RT2w* pvalue F vs RT3h pvalue F vs RT24h pvalue F vs RT2w
Bacteroides;uncultured bacterium 19 20 19 13 0.749 0.749 0.0349

  1. 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.
