目的应用meta分析的方法评价经阴道超声检测宫颈长度预测无症状双胎早产的价值。方法通过电子文献检索有关宫颈长度(cervical length，CL)预测双胎早产的中英文文献，并计算受试者工作特性曲线(SROC)曲线下面积(AUC)并进行比较。结果在20~24w测量宫颈长度，以25mm为界值时，预测34w前早产及以30mm为界值时，预测35w前早产SROC曲线下面积均大于90%。结论于20~24w测量，25mm为界值时，预测34w之前早产及30mm为界值时，预测35w之前早产的准确率较高。
目的應用meta分析的方法評價經陰道超聲檢測宮頸長度預測無癥狀雙胎早產的價值。方法通過電子文獻檢索有關宮頸長度(cervical length，CL)預測雙胎早產的中英文文獻，併計算受試者工作特性麯線(SROC)麯線下麵積(AUC)併進行比較。結果在20~24w測量宮頸長度，以25mm為界值時，預測34w前早產及以30mm為界值時，預測35w前早產SROC麯線下麵積均大于90%。結論于20~24w測量，25mm為界值時，預測34w之前早產及30mm為界值時，預測35w之前早產的準確率較高。

Objective To assess the accuracy of transvaginal sonographic cervical length (CL) in predicting preterm birth in asymptomatic women with twin pregnancies.Methods From a comprehensive literature search articles writ en in Chinese and English were selected that investigated the diagnostic accuracy of CL to predict preterm birth in asymptomatic women with twin pregnancies.The area under the SROC curve was used as the final indicator of test performance. Results Twenty-one studies met the inclusion criteria. At 20~24 weeks' gestation,the AUC of a CL≤25 mm in predicting preterm birth<34 weeks'gestation and a CL≤30 mm in predicting preterm birth<35 weeks'gestation are more than 90%. Conclusion Through transvaginal sonographic CL 20~24 weeks' gestation ,a CL≤25 mm in predicting preterm birth<34 weeks'gestation and a CL≤30 mm in predicting preterm birth<35 weeks'gestation are more accurate.
