There is an association between first-trimester CL and risk of short cervix in the second trimester. Once short CL was observed, risk of preterm delivery was greatly increased. However, whether universal CL screening should be implemented in this low-risk population depends on cost-benefit analysis taking into account the low proportions of women with short CL and at risk for preterm delivery.
