Development and validation of the BPDKC model for predicting sarcopenic knee osteoarthritis in community-dwelling older adults: a cross-sectional study
The BPDKC model is a simple, internally validated, and clinically practical tool for SPKOA risk prediction in community-dwelling older adults. Its high specificity and calibration support its utility in ruling out low-risk individuals, while its web-based implementation facilitates integration into primary care workflows. Although sensitivity remains limited-reflecting the challenge of case-finding in low-prevalence settings-the model offers meaningful clinical value for targeted screening and early intervention. External validation in diverse populations is recommended prior to broader implementation.
