Mean CL at diagnosis was significantly shorter in the cerclage group (5\u00a0mm) compared with the progesterone group (12\u00a0mm). Regardless of treatment there was no difference in the rate of spontaneous preterm delivery at &lt;32\u00a0weeks of gestation in women with CL\u00a0\u2265\u00a09\u00a0mm at screening (11% and 12% in the cerclage and progesterone groups, respectively). In contrast, in the subgroup with CL\u00a0\u2264\u00a08\u00a0mm cervical cerclage resulted in significantly lower rates of spontaneous preterm delivery at &lt;32\u00a0weeks of gestation compared with progesterone treatment (20% and 45%, respectively,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0=\u00a0.009) and the median gestational age at birth was significantly greater (37\u00a0weeks vs 36\u00a0weeks, respectively,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0=\u00a0.013).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The majority of asymptomatic singleton pregnancies with short CL will remain undelivered until 32\u00a0weeks of gestation whether treated with progesterone or cerclage.
