Multi-body-site microbiome of Venezuelan Amerindian villages

sex differs between samples of the same subject id (13 subjects, 38 samples) — sex withheld; subject ids shared by samples of both sexes (12 ids, 34 samples) — ids withheld.

The sources disagree on 46 samples. Where two incompatible values exist for one sample (or one person's samples disagree on sex), neither value is published: the field is left empty here, in the sample sheet and in the downloads. Both sides, with their sources, are in gut_metadata_contradictions.parquet of the data package (what counts as a contradiction).

16 of 166 people sampled more than once (42 samples; median 2, up to 4 per person) · follow-up median 12.5 y (max 53.0 y) · median interval between samples 6.0 y (time from age at collection). Schedule stated by the source: “Subjects recruited/sampled in 2015 (before low-exposure villages' Ivermectin treatment) and again in 2016 (after all villages received Ivermectin treatment).”.

Each row is one person (16 shown); dots are samples at days since that person's first sample; rows of one family are adjacent and coloured by role (mother, father, child, twin).

Yekwana/Sanema villagers: 28 families, 28 houses, 8 villages, 2 ethnic groups (Family_ID, House_ID, Village, Ethnicity) · 28 families with 116 sampled people · 35 shared settings.

member · 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: 24 of 28 families (one per family structure, then more) · 8 of 35 shared settings. 166 people in the project overall.
