longitudinal
60 of 60 people sampled more than once (178 samples; median 3, up to 3 per person) · follow-up median 15 d (max 46 d) · median interval between samples 8 d (time from collection dates).
Each row is one person (36 shown of 60); dots are samples at days since that person's first sample.
Genera, mean relative abundance over 159 profiled gut samples of this project (Sandpiper SingleM profiles, GTDB R232; low-depth and non-metagenome profiles left out).
