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):

本项目采用“ISGLS标准”,作为本项目中术后肝功能衰竭的诊断标准及分级标准。诊断标准为术后第5天和之后出现的凝血酶原时间国际标准化比值(PT-INR)异常升高和高总胆红素血症。

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):

This project utilizes the "ISGLS criteria" as the diagnostic and grading standards for postoperative liver failure. The diagnostic criteria consist of abnormally elevated prothrombin time international normalized ratio (PT-INR) and hyperbilirubinemia occurring on or after the fifth postoperative day

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):

基于多模态融合的术后肝功能衰竭预测结果

Index test:

Prediction results of post-hepatectomy liver failure based on multimodal fusion

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)

存在影像证实的肝占位并接受肝切除术的患者。

例数:

Sample size:

1000

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 liver mass confirmed by imaging and who subsequently underwent hepatectomy.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

非手术治疗的肝占位患者

例数:

Sample size:

0

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

Patients with hepatic mass who are receiving non-surgical treatment
