Relative expression levels of (A) lncRNAs (NEAT1, MALAT1) and miRNAs (miR-30a-5p, miR-30d-5p), (B) target mRNAs (AR, FST and IRS-2) in peripheral blood leukocytes obtained from controls (n = 31), non-obese (n = 32) and obese (n = 41) PCOS patients. Horizontal lines inside the box plots represent the median; the boxes mark the interval between the 25th and 75th percentiles. The whiskers denote the intervals between the 10th and 90th percentiles. Filled circles indicate data points outside the 10th and 90th percentiles. NEAT1: nuclear enriched abundant transcript 1, MALAT1: metastasis associated lung adenocarcinoma transcript 1, AR: androgen receptor, FST: follistatin and IRS-2: insulin receptor substrate-2. Significant P-values are indicated on graph at p < 0.05.
