A transabdominal approach was used in 9006 (96.3%), including 682 (7.3%) TVCL combined with TACL. There were 349 (3.7%) women who had TVCL only. The median TACL was longer (40\u2009mm) than the TVCL (38\u2009mm). In 682 paired TACL and TVCL measurements, TACL &lt;35\u2009mm correctly identified 96.2% of pregnancies with TVCL &lt;25\u2009mm, compared with 65.4% of cases when using a TACL &lt;30\u2009mm.
