随机方法(请说明由何人用什么方法产生随机序列):

我们使用Stata Version 14 (StataCorp LP, College Station, TX, USA)生成的随机列表,以门诊就诊时间按区块6随机分配

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

The randomized allocation was stratified in permuted blocks of size six using a list produced by Stata Version 14 (StataCorp LP, College Station, TX, USA).

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

由于干预的性质,两名牙医和两名牙科保健师对分组未保持盲法。但评估侧位x线片图像的两名放射科医师,以及负责结果评估的两名经过专门培训的护士均保持盲法。

Blinding:

The two dentists and two dental hygienists were precluded from being masked from group allocation due to the nature of intervention. But the two radiologists who assessed the images of lateral cephalometric radiographs, and the two specially trained nurses who were responsible for outcome assessments were all blinded to treatment modalities.
