From: Dynamic evolution of osseous structure in osteonecrosis of the femoral head and dynamic collapse risks: a preliminary CT image study

Indicator Area under ROC curve P 95% CI
Bone mineral density 0.323 0.032 0.174~0.473
Volume of sclerotic bone 0.600 0.225 0.434~0.766
Volume of soft tissue 0.573 0.377 0.410~0.736
Combined volume (sclerotic bone and soft tissue) 0.654 0.061 0.501~0.808
Composite index (logistic regression model integrating bone mineral density and volume of sclerotic bone) 0.765 0.001 0.630~0.900
