      Strength 1. A variety of medical information is recorded in the database, which has provided abundant exposure factors and outcomes, and all the medical information is connected by the health file number;
      2. The chronic disease patients are followed up and managed, which provides multiple repeated data for test.
      Weakness 1. The clinic information outside Yinzhou District is unavailable;
      2. Some data is not structurized and standardized in the database (like compliants, hospitalization summary, examination, etc.) with certain missing value.
