From: Early prediction of outcome after severe traumatic brain injury: a simple and practical model
Our proposed model Estimate (95 % confidence interval) | Previously validated core model Estimate (95 % confidence interval) | Previously validated extended model Estimate (95 % confidence interval) | |
|---|---|---|---|
Sensitivity | 72.3 % (66.4–77.6 %) | 83.8 % (78.7–88.0 %) | 92.7 % (88.6–95.4 %) |
Specificity | 62.5 % (54.9–69.6 %) | 47.7 % (40.2–55.4 %) | 44.3 % (36.9–52.0 %) |
Positive predictive value | 74.0 % (68.1–79.2 %) | 70.3 % (64.8–75.3 %) | 71.1 % (65.9–75.8 %) |
Negative predictive value | 60.4 % (52.9–67.5 %) | 66.7 % (57.6–74.7 %) | 80.4 % (70.9–87.5 %) |
Correct classification | 68.3 % (63.7–72.6 %) | 69.3 % (64.7–73.5 %) | 73.2 % (68.7–77.2 %) |
