随机方法(请说明由何人用什么方法产生随机序列): |
每位参与者将接受三次超声检查:一次由 IS-MAN 系统进行,一次由资深放射科医生进行,一次由初级放射科医生进行。这三次检查的顺序将在六种可能的检查顺序中随机确定。为确保各检查顺序的均衡性,将采用以 6 为单位的区组随机化方法。分配情况将通过中央随机化系统进行保密处理。 上述所有随机序列均由专业统计师通过计算机算法生成。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Each participant will undergo three ultrasound examinations: one performed by the IS-MAN system, one by a senior radiologist, and one by a junior radiologist. The order of the three examinations will be randomized among the six possible examination sequences. To ensure balance across examination sequences, block randomization with a block size of 6 will be used. Allocation will be concealed through a central randomization system. All of the above-mentioned random sequences were generated by professional statisticians using computer algorithms. |

盲法: |
1. 图像评估盲法:所有超声图像均进行去标识化处理,阅片者对受试者临床信息、操作者身份、扫查方式及数据顺序均保持盲态。 2. 操作者隔离盲法:各操作者之间实行物理隔离,在某一组进行扫查时,其余组别无法观察检查过程及图像结果,以避免学习效应及信息泄露。 3. 参考标准盲法:参考标准由独立专家组建立,专家不参与图像采集及后续统计分析过程,且独立专家组对扫查来源、扫查顺序保持盲态。 4. 随机分配隐藏:随机序列由独立统计学人员采用计算机生成并单独保管。研究实施人员及操作者在受试者纳入前均无法获知随机分配结果。随机信息仅在检查实施前由指定协调员按顺序告知相关操作者。 通过随机化、交叉对照及盲法设计,本研究旨在最大程度降低选择偏倚、信息偏倚及观察者偏倚,提高研究结果的真实性与可靠性。 |

Blinding: |
1. Image assessment blind method: All ultrasound images are anonymized. The readers remain blinded to the clinical information of the subjects, the identity of the operators, the scanning methods, and the sequence of the data. 2. Operator isolation blind method: Physical isolation is implemented among different operators. When one group is performing scanning, the other groups cannot observe the examination process and image results, in order to avoid learning effects and information leakage. 3. Reference standard blind method: The reference standard is established by an independent expert panel. The experts do not participate in the image collection and subsequent statistical analysis process, and the independent expert panel remains blinded to the source of the scans and the scanning sequence. 4. Random allocation concealment: The random sequence is generated by independent statisticians using a computer and kept separately. The research implementers and operators cannot know the random allocation results before the subjects are included. The random information is only informed to the relevant operators in sequence by the designated coordinator before the examination is implemented. Through randomization, cross-comparison, and blind method design, this study aims to minimize selection bias, information bias, and observer bias, and improve the authenticity and reliability of the research results. |
