隐蔽分组方法和过程:
|
采用“按顺序编码、密封、不透光的信封”的方法对随机方案进行隐藏。一位研究者在诊室筛选、登记参与者。另一位不参与数据管理的研究者,利用SPSS 20.0软件将预先设定的240名人群编号随机平均分成0,1,2,3四组。该四组的随机数字将封存在不透光的信封中,信封表面标注连续的数字编码。参与筛选、登记的研究者根据病人的登记号依次打开信封。

Process of allocation
concealment:
|
One researcher screens and enrolls participants at the clinic. Another researcher randomly assigns all eligible patients to one of four treatment groups in a 1:1:1:1 ratio using SPSS 20.0 software (SPSS Inc., Chicago, IL, USA). The random numbers in sealed opaque envelopes are designed to four groups. All envelopes are numbered consecutively. The researcher, who enrolls the eligible patients, opens the envelopes according to patients' registration order numbers, and then assigns the patients to group 0, 1, 2 or 3 in accordance with the group number inside.

盲法:
|
该临床研究为单盲设计。入组病人、数据管理人员及数据分析人员为盲者。治疗医师为非盲者。在整个临床研究过程中,治疗医师与数据管理人员不能交换信息。
|
Blinding:
|
We applied a single-blind design in which the study patients, data collocation staff, and data analysts are blinded during the study protocol. The therapists are not blinded to the treatments they deliver because treatment manipulation makes it impossible. During the intervention, therapists and data collection staff are instructed not to exchange information with each other nor communicate with the study patients.

揭盲或破盲原则和方法:
|
揭盲:该研究进行两次揭盲。当数据疑问清理完毕,人群划分决议签署,统计分析计划签署以及数据库锁定后,召开盲态审核会议进行一次揭盲,研究者、数据管理人员、统计分析人员共同参与揭盲过程,揭盲后,将合并了人群划分信息和分组信息的数据交由统计分析人员进行统计分析。在统计分析结束且所有研究者确认统计分析的结论后进行二次揭盲,获得真实的分组信息。统计分析人员报告二次盲底,将分组代码替换为真实组别,完成报告定稿并签字。
破盲:当受试者出现严重不良事件或其他危重紧急的情况时,医生的进一步诊疗需要依据其所接受的干预信息时,可拆启不透光的信封进行破盲。

Rules of uncover or
ceasing blinding:
|
The study is uncovered twice. When there are no doubts of the data, the allocation, the statistical analysis plan, and database is locked, the first uncovering meeting is held. Researchers, data collocation staff, and data analysts participate uncovering process, Data analysts receive all combined information to analyze in this uncovering stage. After the statistical analysis is completed and the conclusion of the statistical analysis is confirmed by the researchers, the second uncovering meeting is held. The real grouping information is obtained and the data analysts complete the final report and sign it in this meeting.
When the participant has a serious adverse event or other critical emergency, the doctor's further treatment should be based on the intervention information received by the participant. The doctor can open sealed opaque envelope to obtain the information on the intervention in participant.

统计方法名称:
|
采用SPSS 20.0软件进行数据处理。在这个试验中,我们主要观察指标是匹兹堡睡眠质量指数得分。我们将治疗有效定义为匹兹堡睡眠质量指数在治疗后下降2分或以上。首先,使用描述性统计对每个组的基线特征进行分析。然后进行重复测量分析,比较治疗组和对照组(电针结合酸枣仁汤组与假针刺组、电针组与假针刺组、酸枣仁汤组与假针刺组)在不同时间点(第2、4、8、12周)的差异。如果发现有显著差异,下一步是对三组治疗的有效性进行比较。根据Bonferroni校正方法调整多次比较。采用Kruskal-Wallis检验对偏态分布数据进行了分析。数值变量采用方差分析,分类变量采用费雪检验。

Statistical method:
|
In this trial, our primary outcome measure is the Pittsburgh Sleep Quality Index scores. We define the treatment response as a reduction in score on the the Pittsburgh Sleep Quality Index following treatments of two-point or more. First, baseline characteristics are analyzed using descriptive statistics for each group. Then repeated measures analysis is performed to make comparisons among the treatment groups and the control group (EA&SZRD versus sham EA, EA versus sham EA, and SZRD versus sham EA) at different time points (2th, 4th, 8th and12th week). If a significant difference is found, the next step is to make comparisons among the three treatment groups in effectiveness. Multiple comparisons are adjusted according to the Bonferroni correction method. The Kruskal-Wallis test are employed in the analysis of skewed distribution data. Analysis of variance are used for numerical variables, and the Fisher test for categorical variables. The statistician is blinded from the allocation of groups. The SPSS 20.0 software package (SPSS Inc., Chicago, IL, USA) are used to analyze the data
