Follow-up duration was 71.1±23.2 days in fetuses that underwent technically successful intervention and 68.2±24.9 days in comparison group fetuses (P=0.58). Data are presented as mean±SD.
Fetal deaths and fetuses still in utero excluded.
Preintervention/midgestation technically successful intervention versus comparison fetuses.
Follow-up technically successful intervention versus comparison fetuses.
