Quantitative real-time PCR was utilized to examine the relative expression of miR-92a-3p and miR-182-3p.

The expression of miR-92a-3p and miR-182-3p were positively correlated with 1 h OGTT, 2 h OGTT, and HOMA-IR. The ROC curves demonstrated that the areas under the curve (AUCs) of miR-92a-3p, miR-182-3p, and the combination of the two in the diagnosis of GDM were 0.890, 0.813, and 0.921, respectively. Elevated levels of serum miR-92a-3p and miR-182-3p were linked to APOs.
