  1. The effects of gestational DE exposure on fetal body and head parameter (length, width and perimeter) and on umbilical pulse were measured with Doppler ultrasound in control (C) and exposed (E) groups. The linear model was adjusted only for the dam and all data are expressed as median [Q1; Q3] (*p < 0.05, compared with control group)
