longitudinal
30 of 32 people sampled more than once (60 samples; median 2, up to 2 per person) · follow-up median 1 d (max 1 d) · median interval between samples 1 d (time from collection dates). Schedule stated by the source: “Fecal samples collected at baseline (T0) and after a 2-week breakfast intervention (T2) for each participant.” (time origin: intervention_start); stated follow-up 14 d.
Each row is one person (30 shown); dots are samples at days since that person's first sample.
Genera, mean relative abundance over 59 profiled gut samples of this project (Sandpiper SingleM profiles, GTDB R232; low-depth and non-metagenome profiles left out).
