Panel A, PARP gene expression between pregnant women with lower extremity venous insufficiency (VI) and pregnant women health control (HC), as measured by RT‐qPCR. Panel B, Histological images of PARP protein expression showing the relevant immunodetection in the placental villi (C) and the decidual cells (D) in the placentas from women with VI. Panel C, Quantification of the percentages of syncytiotrophoblast, foetal capillary and decidual cells that are positive for PARP. The arrows are the brown coloration indicating the specific protein expression, and 640× is the magnification of histological images. Data shown median and IQR. *P‐value < .05 (Mann‐Whitney U test)
