Risk Prediction System for Metabolic Associated Fatty Liver Disease, a Community-based Cohort Study

The present community-based cohort study enrolls subjects who take physical health examinations at the sub-center outpatient department, Beijing Friendship Hospital. After signing the informed consent, Their previous health physical examination results, which were recorded in the Hospital Information System (HIS) are collected retrospectively. Then, Investigators collect their baseline information, including demographic data, clinical history, physical examination, laboratory results, image logical examination, and so on. Additionally, follow-up surveys will be conducted annually and the information collected is the same as the baseline. The outcome information, including cardiovascular disease, malignancy, liver cirrhosis, liver decompensation, liver transplantation, and all-cause mortality, is obtained from the hospital discharge database and death registration system in Beijing. The study's primary aim is to build a risk-stratified evaluation system for MAFLD through a community population cohort with long-term stable follow-up.
