Dynamics in cervical lengths in the course of routine screening in triplet pregnancies (data provided as median and standard deviation). a Complete study population. b Women with (n = 37, white dots) and without preterm delivery <32 + 0 weeks of gestation (n = 54, black dots). The group of women with preterm delivery includes those with a second trimester miscarriage. c Women with mono-/dichorionic triplets (n = 23, white dots) and trichorionic triplets (n = 55, black dots). The gray bars indicate how many pregnancies were ongoing at this time of measurement (provided in %). Gestational age is plotted on the x-axis
