N and prediction of diabetic and cardiovascular complications. The limitation of this study was that the amount of circumstances and events incorporated and analyzed was reasonably little. Future study shall aim to additional clarify the diagnostic and prognostic abilities of miR-222-3p and expand the investigation into the target genes of miR-222-3p depending on larger sample size and distinctive phenotypes of PCOS to increase the credibility from the outcomes.Supplementary InformationThe on the web version consists of supplementary material readily available at doi. org/10.1186/s12905-022-01912-w. Additional file 1: Fig. S1. Sample size was estimated ahead of time working with Gpower computer software. Extra file two: Fig. S2. Statistical energy of differential expression of miR-222-3p in different groups was estimated using Gpower software. Further file 3. Original data for Fig. 1 and Fig. 2.
