Sampling design and relatedness

longitudinal

10 of 10 people sampled more than once (60 samples; median 6, up to 6 per person) · follow-up median 14 d (max 14 d) · median interval between samples 7 d (time from timepoint numbers, unit from the stated sampling schedule). Schedule stated by the source: “Repeated sampling of same 10 subjects at day 0, 7, and 14 under different storage conditions (same biological sample split across methods/timepoints)”; stated follow-up 14 d.
