Coprococcus is associated with HOMA-IR in humans (correlation across participants with available microbiota and HOMA-IR data) (r = −0.28).
“The change in Coprococcus relative abundance from baseline to week 12 was inversely correlated with the change in HOMA-IR (r = −0.28, p = 0.010), indicating that participants with greater increases in Coprococcus tended to exhibit greater improvements in HOMA-IR.”
