Accuracy of clinician prediction of survival by prognostic confidence in prediction.
aP-value was 0.359 by chi-square test. bAccurate estimation was defined as clinician prediction of survival being within ±33.3% of actual survival. cClinicians’ prognostic confidence was measured by a percent scale from 0% (not at all) to 100% (full confidence).
Fig 2.
Survival according to the accuracy of clinician prediction of survival.
Patients with accurate clinician prediction of survival (CPS), underestimated CPS, and overestimated CPS had median survival times of 6.6 months (95% CI 5.1–8.2), 19.7 months (95% CI 13.6–25.8), and 2.1 months (95% CI 1.5–2.7), respectively. The differences in survival in the three groups were all significant (accurate CPS vs. underestimated CPS: P<0.001; accurate CPS vs. overestimated CPS: P<0.001) by the log-rank test.
