longitudinal — not resolved
50 of 100 people sampled more than once (100 samples; median 2, up to 2 per person). Schedule stated by the source: “Obese minors sampled before and after 1-year lifestyle intervention (OM vs OM...B pairs); healthy minors (HM) sampled once” (time origin: intervention_start); stated follow-up 12 mo.
Genera, mean relative abundance over 96 profiled gut samples of this project (Sandpiper SingleM profiles, GTDB R232; low-depth and non-metagenome profiles left out).
