TPO and polycystic ovary syndrome: A subgroup analysis based on TSH-matching revealed that the higher prevalence of anti-TPO and anti-TG antibodies in women with PCOS was no longer statistically significant in the TSH-matched subgroup (anti-TPO: OR 1.28, 95% CI: [0.86–1.92], p = 0.23; anti-TG: OR 1.43, 95% CI: [0.86–2.37], p = 0.17), in contrast to the TSH-not matched subgroup (anti-TPO: OR 5.27, 95% CI: [3.00–9.27], p < 0.00001; anti-TG: OR 3.26, 95% CI: [1.55–6.86], p = 0.002).
