  1. * In these studies age is reported as median (age range)
  2. # In these studies age is reported as average (age range)
  3. a Metadata were only reported for the American Gut Participants (n = 1375) as participant data for the Human Microbiome Project is restricted access
  4. b These findings only pertain to the urban dwelling Nigerians from this study
  5. c A median or average for age groups was not provided. Infants were defined as < 3 years of age (n = 12) and adults were 5-85 (n = 18)
  6. d These values only pertain to the analysis in the TwinsUK cohort in this paper
  7. e These values are reported for the AVG cohort with regard to cardiorespiratory fitness, but is reflective of all study participants. Total age range for all participants is between 18 and 35 years
