aData based on gas chromatography-mass spectrometry analysis; during their hospital stay, women could be exposed to different MDs containing various plasticizers
bType of MD containing DiNP: simple infusion set
cType of MDs containing TOTM: multi-access infusion set, epidural infusion set and extension tubes
dType of MD containing DINCH: flow regulator; all women exposed to at least one MD containing DINCH had been admitted for pregnancy-related vomiting episodes
