Garg et al., 2018 [77]	case-control study (n = 2090; all female)	−prevalence of PCOS in HS was higher than in patients without HS (9.0% vs. 2.9%; p < 0.0001). −probability of patients with HS having PCOS was 2.14-fold higher (95% CI 2.04–2.24) than in patients without HS	HS is associated with PCOS.
Phan et al., 2020 [76]	Meta-analyses with 5 case-control studies (n = 20,532; all female)	−probability of patients with HS having PCOS was 2.64-fold higher (95% CI 1.69–4.11; p < 0.00001) than in patients without HS	There is a link between HS and PCOS.
