longitudinal
32 of 32 people sampled more than once (64 samples; median 2, up to 2 per person) · follow-up median 3 mo (max 3 mo) · median interval between samples 3 mo (time from visit codes mapped to the stated schedule). Schedule stated by the source: “Two faecal samples per participant: baseline (CID1) and after a 12-week dietary intervention (CID5).” (time origin: intervention_start); stated follow-up 3 mo.
Each row is one person (32 shown); dots are samples at days since that person's first sample.
