The Potential Value and Impact of Diagnostic Biomarkers for MAFLD Using Machine Learning Methods

Study Overview
=================
Brief Summary
-----------------
This is a case-control study that aims to build a predictive model for MAFLD based on machine learning.

Detailed Description
-----------------
Metabolic dysfunction-associated fatty liver disease (MAFLD) also known as non-alcoholic fatty liver disease (NAFLD), is one of the most prevalent liver diseases worldwide with high prevalence and economic burden, which affects 25% of global adult population. Despite extensive research on understanding the inner pathophysiology of MAFLD, it still keep growing with no approval therapy. Therefore, preventive measures are particularly important in diagnosing MAFLD. So far the liver biopsy is still the gold standard for diagnosis of MAFLD, however considering the invasive process and potential risks, it still has low acceptance for asymptomatic patients, thus non-invasive methods are necessary for this reason. The purpose of this study is to establish a prediction model to identify MAFLD patients, which can accurately predict whether the participants have MAFLD according to the relevant metabolic indicators of the participants, without the need for invasive examinations such as tissue biopsy.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area under cure | Area under cure(AUC) was defined as the area enclosed by the coordinate axis under the receiver operating characteristic curve, with values ranging from 0.5 to 1.0. The closer the AUC is to 1.0, the higher the authenticity of the detection method; the closer to 0.5, the lower the authenticity of the detection method; when equal to 0.5, the authenticity is the lowest and has no application value. | 2022-2024 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Accuracy | The proportion of the number of correctly classified samples to the total number of samples. | 2022-2024 | 
| Precision | The proportion of data that is actually positive among the data that is determined to be positive. | 2022-2024 |
