盲法:

本研究采用单盲法。对干预者(正畸医师)和受试者(患者)不设盲,这是由于两组治疗方案明显不同,正畸医师和患者很容易识别分组。对资料分析者设盲,具体方法为隐去头颅侧位定位片中的患者信息,以研究编号代替。

Blinding:

Blinding of either orthodontists or participants is not possible because the treatment protocols in two groups were different. However, blinding will be used during the cephalometric analysis. All cephalometric films will be deidentified by opaque tape and replaced by research numbers, and then disarranged before tracing. The investigator who is responsible for measuring do not know the grouping of the cephalometric radiographs, which looked similar.
