Summary
This study identifies key risk factors for lichenoid vulvar disease (LVD) in women, developing a Gradient Boosting Machine (GBM) model for early detection. The GBM model effectively predicts LVD risk, aiding in timely intervention and prevention strategies.
Area of Science:
- Gynecological Health
- Dermatology
- Predictive Modeling in Medicine
Background:
- Lichenoid vulvar disease (LVD) presents complex risk factors, necessitating personalized risk assessment models.
- Existing research on LVD risk factors and predictive models is limited both nationally and internationally.
- This study is the first systematic investigation into LVD risk factors and the development of a predictive model.
Purpose of the Study:
- To identify and analyze risk factors associated with LVD in women.
- To construct an evidence-based warning model for early LVD risk detection in high-risk populations.
- To enhance clinical identification, prediction accuracy, and diagnostic proficiency for LVD.
Main Methods:
- Retrospective analysis of 2990 patients (1218 controls, 1772 LVD cases) from West China Second Hospital (2013-2017).
- Collection and comparison of routine examination data to identify significant risk factors.
- Development and evaluation of six predictive models (logistic regression, random forests, GBM, adaboost, XGBoost, CatBoost) using ROC curves and AUC.
Main Results:
- Significant risk factors for LVD include vaginitis, urinary incontinence, environmental humidity, spicy diet, coffee intake, sleep duration, diabetes, smoking, autoimmune diseases, menopause, and hypertension.
- The Gradient Boosting Machine (GBM) model demonstrated superior predictive performance (AUC, accuracy, sensitivity, F1-score) compared to other models.
- Menopausal status and autoimmune diseases were identified as the strongest positive predictors of LVD.
Conclusions:
- A predictive warning model for LVD, based on evidence-based medicine, can effectively identify high-risk individuals.
- Early identification facilitates timely preventive measures, crucial for reducing LVD incidence in women.
- The developed model holds significant potential for clinical application and reducing the overall disease burden.
