隐蔽分组方法和过程:
|
本试验将采用分层区组随机化和双盲方法,以最大程度地避免在受试者的入组、治疗和评价因治疗方案的可预测性而选择性入组或对试验结果的干扰,造成可能发生的潜在偏倚。
本试验采用中央随机化系统(IWRS)进行随机,随机盲底和编药盲底由统计单位通过SAS软件产生并导入IWRS。受试者筛选合格以后,研究人员登录IWRS,录入受试者信息,获取随机号和药物编号,根据药物编号发放药物。

Process of allocation
concealment:
|
This trial will use a stratified block randomization and double-blind method to minimize the selection of participants or interference with the trial results due to the predictability of the treatment regimen in the enrollment, treatment and evaluation of subjects. cause potential bias that may occur.
The trial was randomized by the central randomization system (IWRS). The blind base of randomization and the blind base of preparation of drugs were generated by the statistical unit through SAS software and imported into IWRS. After the subjects are screened and qualified, the researchers log in to IWRS, enter the subject information, obtain the random number and drug number, and distribute the drugs according to the drug number.

盲法:
|
盲法
① 盲法设计:双盲,即研究者和受试者在整个临床试验过程中均处于盲态中。
② 编盲:药物现场编盲由统计单位人员和申办单位与本试验无关人员参加,将已形成的药物编号粘贴在标签上。编盲过程形成编盲记录保存。

Blinding:
|
Blind
① Blind design: double-blind, that is, the investigator and the subjects are blinded throughout the clinical trial.
② Blind coding: The on-site blind coding of drugs was attended by the personnel of the statistical unit and the sponsor unrelated to the trial, and the formed drug number was pasted on the label. The process of compiling blindness forms the record keeping of compiling blindness.

揭盲或破盲原则和方法:
|
应急信件与紧急揭盲:本试验采用线上紧急揭盲方式,受试者信息保存于 IWRS 中。在紧急情况下,研究者认为知晓受试者所服用药物有利于不良事件的处理时,由主要研究者在 IWRS 中进行紧急揭盲。一旦被揭盲,该编号受试者将退出试验,按脱落病例处理,研究者应将退出原因记录在病例报告表中。
揭盲规定:本研究采用二级揭盲法。一级揭盲于统计计划书、数据审核报告定稿并数据库锁定后进行,揭晓随机号所对应的组别代码,以便对全部数据进行分组后的统计分析。统计分析完成后进行二级揭盲,揭晓组别代码对应的药物。揭盲文件由主要研究者、申办单位、统计人员共同签署。

Rules of uncover or
ceasing blinding:
|
Emergency letter and emergency unblinding: This trial adopts an online emergency unblinding method, and the subject information is stored in IWRS. In emergencies, when the investigator believes that knowing the drug the subject is taking is beneficial for the management of the adverse event, the principal investigator conducts emergency unblinding in IWRS. Once unblinded, the numbered subject will withdraw from the trial and be treated as a dropout case, and the investigator should record the reason for withdrawal in the case report form.
Unblinding regulations: This study used a secondary unblinding method. The first-level unblinding is carried out after the statistical plan, the data audit report is finalized and the database is locked, and the group code corresponding to the random number is revealed, so that all data can be grouped for statistical analysis. After the statistical analysis was completed, secondary unblinding was performed to reveal the drugs corresponding to the group codes. The unblinding document was signed by the principal investigator, the sponsor, and the statistician.

SAS?9.4软件
所有的统计检验均采用双侧检验,P值小于或等于0.05将被认为所检验的差别有统计意义(特别说明的除外)。
描述性分析:计数资料采用例数及构成比描述,计量资料采用均数、标准差、最大值、最小值描述,非正态分布资料采用中位数、第25及第75分位数描述。
对两组一般情况的比较将根据指标的类型采用适当的方法进行分析,定量资料的组间比较采用方差分析或Wilcoxon秩和检验,分类数据采用卡方检验或精确概率法,等级资料采用Wilcoxon秩和检验或CMH检验。

Statistical method:
|
SAS? 9.4 software
All statistical tests were two-sided, and a P value less than or equal to 0.05 was considered statistically significant for the differences tested (unless otherwise stated).
Descriptive analysis: enumeration data were described by the number of cases and constituent ratios, measurement data were described by mean, standard deviation, maximum and minimum values, and non-normally distributed data were described by median, 25th and 75th quantiles.
The comparison of the general conditions of the two groups will be analyzed by appropriate methods according to the types of indicators. The comparison between groups of quantitative data will use analysis of variance or Wilcoxon rank sum test, the categorical data will use the chi-square test or the exact probability method, and the rank data will use the Wilcoxon rank test. and inspection or CMH inspection.
