盲法:

为降低可能出现的临床试验研究人员的主观偏差和个人经验对试验结果的影响,本次试验采用盲法设计。负责筛选的临床研究者与负责样本检测者、EIT和DECT实施者分别为不同人员,即检测者、操作者对相关的患者信息处于盲态。严格按照试剂说明书以及EIT和DECT操作、软件分析的要求进行,研究过程中得到的结果,由另一研究人员协助如实报告数据,最后由另一临床研究者进行数据录入汇总。研究过程中不能相互透露与本项目相关的任何信息。

Blinding:

To reduce the possible influence of subjective biases and personal experience of clinical trial researchers on the trial results, a blinded design was adopted in this trial. The clinical researchers responsible for screening and the sample testers, EIT and DECT implementers are different personnel, that is, the testers and operators are blind to the relevant patient information. The research was conducted strictly in accordance with the reagent instructions as well as the requirements for EIT and DECT operations and software analysis. The results obtained during the research process were reported truthfully with the assistance of another researcher, and finally the data was entered and summarized by another clinical researcher. During the research process, no information related to this project should be disclosed to each other.
