Sampling design and relatedness
longitudinal — not resolvedFMT donor → recipient
14 of 21 people sampled more than once (34 samples; median 2, up to 5 per person).
Schedule stated by the source: “pre-FMT and post-FMT timepoints per recipient” (time origin: FMT procedure).
Evidence of fmt donor recipient structure.
donorrecipient · circles are people (pale = no sequenced sample), arrows run donor → recipient and parent → child, curved lines join twins, partners and siblings, squares are shared settings or families without recorded roles. Shown: 6 linked groups from explicit relations. 21 people in the project overall.
