PD, primary dysmenorrhea; HC, healthy controls; PGF , prostaglandins F ; VAS, visual analogue scale; SAS, self‐rating anxiety scale; SDS, self‐rating distress scale; se, standard error.
The comparisons of subjects' basic information were performed between PDM and HC groups using two‐sample t test. P < 0.05 was considered significant. False discovery rate (FDR) was used to correct for multiple comparisons.
