Reviewer 2 Report

This is a well conducted meta-analysis and a useful contribution to the literature. The authors recognise the limitations of the available evidence and the paucity of studies available. One possible confounder is whether treatment of the PCOS might influence the presence of PD. For example, metformin, by reducing insulin resistance, might lower the prevalence of PD in these patients. Metformin is widely used in the management of PCOS. Future research should investigate whether particular PCOS treatments influence PD.
