In contrast, several taxa were positively associated with PCOS, including Acidaminococcus fermentans (OR = 1.454; 95% CI: 1.002–2.111; P = .049), Proteus (OR = 1.564; 95% CI: 1.002–2.442; P = .049), and K10 (OR = 1.609; 95% CI: 1.118–2.315; P = .011), indicating possible contributions to PCOS pathogenesis. This evidence concerns the gene KRT10 and polycystic ovary syndrome.
