Figure 2

Patient grouping and estimated probabilities of a RC tear. Rotator cuff (RC) tears or no RC tears were diagnosed according to magnetic resonance arthrography and compared to the predicted probabilities of a RC tear, based on the prediction model. The X-axis represents the patients diagnosed with a RC tear or with no RC tear, according to magnetic resonance arthrography. The Y-axis represents the predicted probabilities of a RC tear according to the prediction model. The box represents graphically 50% of the patients; the heavy line inside the box is the median.
