简要总结
Psoriasis is a long-term inflammatory skin disease that can affect overall health. People with psoriasis have a higher risk of developing insulin resistance, a condition in which the body does not respond properly to insulin. Insulin resistance can increase the risk of diabetes, heart disease, and other serious health problems. Because insulin resistance often develops without clear symptoms, many patients are not diagnosed early.
The purpose of this study is to identify which patients with psoriasis are more likely to develop insulin resistance and to create a tool that can help doctors estimate this risk for individual patients. The study will use existing medical records from two medical centers. Researchers will analyze information such as age, body weight, psoriasis severity, blood test results, other medical conditions, and medication history.
Machine learning methods will be used to analyze these data and build a prediction model. The model will be designed to be easy to understand, so doctors can see which factors contribute most to insulin resistance risk.
This study does not involve any new treatments or procedures. All patient information will be anonymized to protect privacy. The results may help doctors identify high-risk patients earlier and support timely monitoring and preventive care.

结局指标
主要结局
Insulin Resistance Status Assessed by the TyG Index
时间窗: At baseline (using existing medical record data collected between January 2015 and June 2025)
Insulin resistance will be evaluated using the triglyceride-glucose (TyG) index, calculated from fasting triglyceride and fasting plasma glucose levels obtained from medical records. Participants will be classified as having insulin resistance or not based on a predefined TyG index cutoff value (TyG ≥ 8.5)
