Table 4
Mean risk estimates of operative mortality for patients who died (6.1%) and those who survived based on the 121 cases constructed with real patient data
| Model | Surgeon 1 | Surgeon 2 | Surgeon 3 | Surgeon 4 | All 4 surgeons | |
|---|---|---|---|---|---|---|
| **Significant differences between the categories `patients died' and `patient survived' for the model: t (119) = 3.29, p<0.001 and for surgeon 1 t (116) = 5.1, p<0.001, surgeon 2 t (119) = 2.38, p<0.05, surgeon 3 t (118) = 5.83, p<0.001, and surgeon 4 t (119) = 2.78, p<0.01. | ||||||
