诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

5名经验丰富的肝脏病理学家,按照AILD的组织学标准进行评估,意见一致或大于4/5的诊断意见为诊断金标准。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

According to the histological standard of AILD, five experienced liver pathologists assessed that the diagnostic opinions with the same opinion or more than 4/5 were the diagnostic gold standard.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

采用基于实例化学习算法的CLAM算法对数字化病理图片进行智能分析和初步诊断。主要包括训练和验证两个步骤:使用训练集数据对模型进行训练,通过k折交叉验证等方式调整模型参数,避免过拟合现象,优化模型性能。使用验证数据集对训练好的模型进行验证。其中,训练集和测试集按照4:1的比例进行划分,因此分别患者例数分别为1200:300。在训练过程中,设置k=5,使用五折交叉验证调整模型参数,即每次训练中训练集的4/5用来训练模型,1/5用来验证模型性能。

Index test:

The CLAM algorithm based on the instantiated learning algorithm was used to intelligently analyze and make preliminary diagnosis of digital pathological images. It mainly includes two steps: training and validation: using the training set data to train the model, adjusting the model parameters through k-fold cross-validation, etc., to avoid overfitting and optimize the model performance. Use the validation dataset to validate the trained model. Among them, the training set and the test set are divided according to the ratio of 4:1, so the number of patients is 1200:300 respectively. During the training process, k=5 is set and the model parameters are adjusted using five-fold cross-validation, that is, 4/5 of the training set in each training is used to train the model, and 1/5 is used to verify the model performance

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

患有自身免疫性肝炎AIH、原发性胆汁性胆管炎PBC、原发性硬化性胆管炎PSC及上述疾病重叠发生的重叠综合征,符合前述纳入排除标准的患者

例数:

Sample size:

1200

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Patients with autoimmune hepatitis AIH, primary biliary cholangitis PBC, primary sclerosing cholangitis PSC and overlap syndrome caused by the above diseases meet the above inclusion and exclusion criteria.
