  • For variables with a skewed distribution (triglycerides, CRP, IL-6, LPS, %HAM56 and adiponectin): Wilcoxon rank sum test, median (Q1–Q3) shown. For other variables: ANCOVA adjusting for age and sex, adjusted mean (SE) shown.

  • Numbers in bold indicate significance at the 0.05 level.

  • Age LO, age below population median; Age HI, age at or above the population median; Akk LO, A. muciniphila below the median; Akk HI, A. muciniphila at or above the median; DXA, dual energy X-ray absorptiometry; HOMA-IR, Homeostasis Model Assessment of Insulin Resistance Index; hs CRP, high sensitivity C reactive protein; LPS, lipopolysaccharide; scWAT, subcutaneous white adipose tissue.
