Machine learning for oral frailty factors in hospitalized schizophrenia patients: two-stage feature selection and SHAP analysis (opens in new tab)

BackgroundLong-term hospitalized patients with schizophrenia (SZ) often experience significant oral health problems, and oral frailty (OF) can further exacerbate the decline in their quality of life. However, the status and key influencing factors contributing to OF in this population remain insufficiently explored. Most existing studies rely on traditional regression models, which are prone to overfitting when processing high-dimensional data, making accurate risk identification difficult. T...
