Group:

Group A:Cervical dilation group

Sample size:

干预措施:

于LEEP术后3-4周、5-6周和7-8周共扩张3次,3次为一疗程。扩张过程中使用的金属Hegar宫颈扩张棒规格为别为:2.5(2.5mm)、3(3mm)、3.5(3.5mm)、4(4mm)和4.5(4.5mm)号。

随机方法(请说明由何人用什么方法产生随机序列):

由研究负责人使用SPSS Statistics 22.0生成随机种子,创建包含1-86个自然编号的随机数字变量,通过软件将序列随机分配为1(试验组)、2(对照组)两组。

Randomization Procedure (please state who generates the random number sequence and by what method):

The research leader used SPSS Statistics 22.0 to generate random seeds and created random number variables containing 1-86 natural numbers. The sequences were randomly assigned into two groups, 1 (experimental group) and 2 (control group), using software.

是否公开试验完成后的统计结果:

盲法:

结局评估人员全程不知晓分组信息,记录随访信息;数据统计人员独立完成盲态分析。

Blinding:

The outcome evaluators did not know the group information throughout the whole process and recorded the follow-up information. The data statistician independently completed the blind analysis.
