They had transvaginal ultrasound for evaluation of the uterocervical angle and the cervical length between at 30 and 32, 32<jats:sup>+1<\/jats:sup> and 34, and 34<jats:sup>+1<\/jats:sup> and 36<jats:sup>+1<\/jats:sup>\u00a0weeks of pregnancy.

A uterocervical angle of 105\u00b0 or more predicted preterm birth with sensitivity and specificity of 86.1% and 60.4%, respectively.
