2. Fig 1
Receiver operating characteristic curve for 30-day mortality after surgery for fractured neck of femur. The line of identity, which represents a non-discriminatory test, is shown with a dashed line. A perfect test would follow a right-angle with an area under the curve of 1. The area under the curve for POSSUM is 0.62.
