Sampling design and relatedness

longitudinal

6 of 6 people sampled more than once (30 samples; median 5, up to 5 per person) · follow-up median 1 d (max 1 d) · median interval between samples 1 d (time from timepoint labels). Schedule stated by the source: “Single fecal donation per subject, fermented ex vivo in bioreactors with samples taken at 0h and 24h of colonic incubation” (time origin: other).

Details
Archive description

Using the clinically predictive ex vivo SIFR technology (Systemic Intestinal Fermentation research), we examined how YP influences the microbiome of older human adults (50-65 years, n = 6), comparing its effects to whey protein isolate (WPI) and soy protein isolate (SPI).

How this project entered the registry
