  2. a 49 participants are mothers of the twins, for which no age is reported
  3. b These values are reported for the healthy weight cohort, but is reflective of all study participants
  4. c Metadata were only reported for the American Gut Participants (n = 1375) as participant data for the Human Microbiome Project is restricted access
  5. d These values only pertain to the analysis in the TwinsUK cohort in this paper. Other studies were included, but Christensenellaceae was not reported
