Women with singleton gestation and preterm contractions between 24\u2009+\u20090 and 33\u2009+\u20096\u00a0weeks\u2019 gestation were included. For the UCA measurement, a line is placed from the internal os to the external os irrespective of whether the cervix is straight or curved. A second line is drawn to delineate the lower uterine segment. The angle between the two lines is the UCA measurement.

At the time of UCA measurement, median maternal and gestational age was 31.4\u00a0years and 29.7\u00a0weeks\u2019 gestation. Median gestational age at delivery was 35.3\u00a0weeks and the corresponding birth weight 2480\u00a0g, respectively. The UCA measurement in women who delivered within 2\u00a0days, between 3\u20137\u00a0days and after 7\u00a0days was not helpful to distinguish between these three groups [median UCA measurements: 108.5\u00b0, 108.0\u00b0 and 107.3\u00b0 (Kruskal\u2013Wallis test <jats:italic>p<\/jats:italic>\u2009=\u20090.576)].
