Model fitting index | likelihood ratio test | McFadden R² | Cox & Snell R² | Nagelkerke R² | Hosmer-Lemeshow test | ROC curve AUC value (discrimination) | Classification accuracy (predictive accuracy) |
|---|---|---|---|---|---|---|---|
Knee joint injury model (dependent variable: knee joint injury) | χ²=65.580, df = 15, p < 0.001 | 0.049 | 0.066 | 0.088 | χ²=9.25, df = 8, p = 0.327 | 0.71(95%CI: 0.67–0.75) | 72.3%(95%CI: 69.2%−75.4%) |
Ankle joint injury model (dependent variable: ankle joint injury) | χ²=79.663, df = 15, p < 0.001 | 0.066 | 0.079 | 0.111 | χ²=7.81, df = 8, p = 0.453 | 0.75(95%CI: 0.71–0.79) | 76.5%(95%CI: 73.6%−79.4%) |
