Recovery rate and number of trophoblasts identified. (A and B) Patients were analyzed according to gestational age range: 10–11 weeks, 12–14 weeks and 15–20 weeks. (A) Recovery rate and (B) violin plots of circulating extravillous trophoblasts (cEVTs) (solid lines represent median values) in patients with at least one cEVT isolated. A significant linear trend was observed between gestational weeks and recovery rate (chi‐square test for trend, p < 0.01). The number of recovered cEVTs was significantly different comparing 10–11 weeks and 12–14 weeks (Kruskal–Wallis test followed by Dunn's multiple‐comparison test, **p < 0.01). (C and D) Patients were analyzed according to the number of fetuses: Singletons versus Twins. Recovery rate (C) and violin plots (D) of cEVTs (solid lines represent median values) in patients with at least one cEVT isolated. For 365 out of 372 patients, the number of fetuses and fetal gender was available. Patients with an unknown number of fetuses and/or fetal gender were not included. The number of cEVTs is significantly higher in twins compared to singletons (nonparametric Mann–Whitney U test, p < 0.01).
