We excluded women with a history of SPTB. We examined the progression of women with short CL based on the CL measurement and GA at diagnosis. The primary outcome was cervical dilation or spontaneous delivery &lt;24\u2009weeks.<\/jats:p><jats:p>\n          Results\u2003A total of 163 women were included, of whom 27 (16.6%) were ultimately dilated and 4 (2.5%) had pregnancy loss by 24\u2009weeks. The median GA at diagnosis of short CL was 195\/7 (range: 15\u201322) weeks. Women with a CL &lt;15\u2009mm were more likely to have cervical dilation or loss prior to 24\u2009weeks than women whose CL was 15 to 25\u2009mm (42.5 vs. 11.9%, &lt;0.001, adjusted odds ratio: 3.72, 95% confidence interval: 1.52\u20139.09).
