At the family level, Bifidobacteriaceae (coeff = 0.0011, p = 0.00012, Q = 0.192) and Lactobacillaceae (coeff = 0.0010, p = 0.00050, Q = 0.192) associated with increased ALP, the latter driven by the association in PCOS cases (Cases: coeff = 0.0011, p = 0.004; Controls: coeff = 0.00005, p = 0.91), and Peptococcaceae with decreased prolactin (coeff = −0.0011, p = 0.00042, Q = 0.192) (Table S13). The gene discussed is PRL; the disease is polycystic ovary syndrome.
