Strengths and limitations
The main strength of the study is that we focused on the relationship
between ANGPTL4 and PCOS and linked them together for the first time,
and the ANGPTL4 expression in ovarian GCs might be a risk factor for the
occurrence and development of PCOS by taking part in glucose and lipid
metabolism. This has not been confirmed before. But it also had
limitations, small sample size and retrospective study design made it
essential to take further large sample and basic experimental research
to investigate the pathogenesis of ANGPTL4 in PCOS.
