Objectives of Study: |
1. Main objective The core aim of this study is to verify whether the performance of AI algorithms in predicting FEV? and FVC absolute values is non-inferior to the gold standard pulmonary function test: The upper limit of the 95% confidence interval (CI) for the mean difference (AI prediction value - actual pulmonary function measurement) of FEV1 must be <= 0.15 liters The upper limit of the 95% confidence interval (CI) for the mean difference (AI prediction value - actual pulmonary function measurement) of FVC must be <= 0.20 liters 2. Secondary objectives To quantify the actual impact of the visibility of AI predictive information on the decision-making behavior of clinicians and the efficiency of the overall diagnostic process, including: The consistency between the GOLD classification derived from AI prediction values and the results of pulmonary function tests (using the secondary weighted Kappa coefficient); The rate and magnitude of changes in clinical decisions in the two-stage assessment; The time spent on the diagnostic process; The patient-reported experience of the visit; And the consistency and calibration of the algorithm (evaluated through the consistency correlation coefficient CCC, Bland-Altman analysis, and coverage of the prediction interval). |

随机方法(请说明由何人用什么方法产生随机序列): |
1采用中心分层置换区组随机化方法: (1)区组设计:使用动态区块大小(随机选择4或6),以降低分组可预测性。 (2)分配比例:试验组(AI信息可见)与对照组(常规流程)为1:1。 (3)实现方法:由独立统计师使用R软件(如blockrand包)生成不可预测的随机分配序列。 2 分层因素 为确保组间基线均衡,随机化按以下两个因子进行分层: (1)研究中心:用以控制不同中心在患者来源、CT设备及临床实践上的差异。 (2)吸烟包年数:分为“>=10包年”与“<10包年/从不吸烟”两层,此为COPD最重要的风险因素之一。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
1. Adopt the central stratified block randomization method: (1) Block design: Use a dynamic block size (randomly select 4 or 6) to reduce the predictability of the grouping. (2) Allocation ratio: The experimental group (with AI information visible) and the control group (conventional process) are in a 1:1 ratio. (3) Implementation method: An independent statistician uses R software (such as the blockrand package) to generate an unpredictable random allocation sequence. 2. Stratification factors To ensure baseline balance between groups, randomization is stratified according to the following two factors: (1) Research center: To control the differences in patient sources, CT equipment, and clinical practices among different centers. (2) Number of smoking packs per year: Divided into two layers: ">=110 packs per year" and "<10 packs per year / never smoking". This is one of the most important risk factors for COPD. |

盲法: |
1盲法类型 本研究采用部分盲法(Single-Blind),即患者、结局评估者(肺功能质控人员)与统计分析人员对分组信息保持盲态,而负责第二阶段决策的临床医师因需根据分组信息查看不同报告,故无法设盲。 2盲法实施流程 (1)对患者设盲:在知情同意过程中,使用统一的中性语言告知研究流程,不强调分组细节。所有受试者均需完成CT和肺功能检查,以最大程度降低因知晓分组而产生的期望效应差异。 (2)对评估者/统计分析者设盲: 1)数据脱敏与编码:所有用于分析的肺功能数据、AI预测值及临床决策数据在数据库中均使用匿名ID标识,不包含分组信息。 2)盲态维护:负责肺功能报告质控的人员、以及进行最终统计分析的统计师,在整个数据清理和分析阶段均无法接触分组变量。数据库中的分组信息在主要分析完成、数据库锁定后方可解盲。 (3)临床医师的非盲态管理:尽管临床医师在第二阶段知晓分组,但研究通过标准化流程控制偏倚: 1)第一阶段决策盲法:医师在第一阶段(初步决策)时,对所有患者信息(包括分组和肺功能/AI结果)均处于盲态。 2)报告格式标准化:AI报告与肺功能检查报告在eCRF系统中以格式统一的界面呈现,仅内容来源不同,避免因界面差异引入偏倚。 3 破盲管理与应急处理 (1)破盲条件:破盲仅适用于与试验干预相关的严重不良事件(如因AI信息严重偏差导致临床决策错误并造成患者伤害),且必须知晓分组信息方能进行医疗处理时。 4盲法质量控制 (1)盲法效果评估:研究结束后,可对设盲的统计分析师和评估者进行问卷调查,评估其是否猜破分组,并使用统计学方法分析猜破情况与结果评价是否存在关联。 (2)数据一致性检查:由数据管理员在盲态下核对分析数据集与原始数据,确保盲法实施过程未引入数据错配或错误。 |

Blinding: |
1 Type of blinding This study adopts partial blinding (Single-Blind), where the patients, outcome assessors (lung function quality control personnel), and statistical analysts remain blinded to the group information, while the clinical physicians responsible for the second-stage decision-making cannot be blinded as they need to view different reports based on the group information. 2 Blinding implementation process (1) Blinding of patients: During the informed consent process, a uniform neutral language is used to inform the research process without emphasizing the details of the group assignment. All subjects must complete CT and lung function tests to minimize the difference in expectation effects caused by knowing the group assignment. (2) Blinding of assessors/statistical analysts: 1) Data desensitization and coding: All lung function data, AI prediction values, and clinical decision data used for analysis are identified by anonymous IDs in the database and do not contain group information. 2) Maintenance of blinding: The personnel responsible for lung function report quality control and the statistician conducting the final statistical analysis cannot access the group variables during the entire data cleaning and analysis process. The group information in the database can only be unblinded after the main analysis is completed and the database is locked. (3) Non-blinding management of clinical physicians: Although the clinical physicians are aware of the group assignment in the second stage, the study controls bias through standardized procedures: 1) Blinding of the first-stage decision-making: During the first stage (initial decision-making), the physician is in a blinded state for all patient information (including group assignment and lung function/AI results). 2) Standardized report format: AI reports and lung function examination reports are presented in a uniformly formatted interface in the eCRF system, with only the content sources being different to avoid introducing bias due to interface differences. 3 Blinding management and emergency handling (1) Conditions for unblinding: Unblinding is only applicable to serious adverse events related to the trial intervention (such as clinical decision errors caused by significant deviations in AI information and resulting in patient harm), and medical treatment can only be performed when the group assignment information is known. 4 Blinding quality control (1) Evaluation of blinding effect: After the study, a questionnaire survey can be conducted for the blinded statistical analysts and assessors to evaluate whether they guessed the group assignment and whether there is an association between the guess and the result evaluation using statistical methods. (2) Data consistency check: The data administrator checks the analysis data set and the original data in a blinded state to ensure that no data mismatch or errors are introduced during the implementation of the blinding process. |
