Blinding:
|
Patients with primary insomnia: A double-blind design was adopted, and all the patients were blind. Two identical tACS instruments (non-invasive transcranial electrical stimulator GS220) were set in advance according to the requirements of true and false stimulation group, and the output of false stimulation control group was locked to 0. Two instruments were randomly placed in two treatment rooms with the same environment, the patients were randomly grouped into the corresponding treatment rooms for treatment, and the operators completed the treatment of true or false stimulation group according to the same operation flow.
Patients with EDIAD: the patients with EDIAD were randomly divided into abdominal acupuncture test group and sham acupuncture control group, and were only informed to treat in different treatment rooms. Patients, outcome evaluators and third-party statisticians are blind after locking the database.

Statistical method:
|
Both sides are used for inspection. When p value is less than or equal to 0.05, the difference is considered statistically significant.
The dosage of estazolam is expressed in (x±s), and the data of the dosage of estazolam in control group and experimental group at baseline 0 weeks, 1,2,3,4 weeks after treatment and 8 weeks after follow-up are statistically analyzed and compared by single factor repeated measurement variance analysis. Comparison between groups, data in accordance with normal distribution, using two independent samples t test; For comparison of data that do not conform to normal distribution, corrected T test or nonparametric test is adopted; The drug reduction rate of estazolam was expressed in (%), and X2 test was adopted. In the scales (PSQI, BWSQ, HAMA, HAMD) and EEG data, the measurement data is expressed as (x s). By using single factor repeated measurement variance analysis, the scales (PSQI, BWSQ, HAMA, HAMD) and EEG data statistical analysis of control group and experimental group at baseline 0 week, after treatment at the fourth week and during follow-up at the eighth week were compared within the group. Comparison between groups, data in accordance with normal distribution, using two independent samples t test; For comparison of data that do not conform to normal distribution, corrected T test or nonparametric test is adopted; In the scales (PSQI, BWSQ, HAMA, HAMD), the case (%) of counting data is expressed by X2 test. Pearson correlation, multiple regression, coherence and phase lag index are used to construct EEG network The correlation between EEG and other observation indexes, such as dosage of estazolam, drug reduction rate of estazolam, scales (PSQI, BWSQ, HAMA, HAMD), was compared by multiple linear regression or partial correlation analysis.
In general data, the measurement data (such as age, course of disease, time of taking medicine, etc.) are expressed as (x±s), and the data in accordance with normal distribution are compared by t test; For comparison of data that do not conform to normal distribution, corrected T test or nonparametric test is adopted; Counting data (such as gender, family history, etc.) are expressed by use case (%), and X2 test is adopted.
