Models
 TBI Mortality CRASH-basic ↓ ROB: applicability [some mild TBI], self-fulfilling prophecy Moderate 14-day mortality: AUC 0.8–0.82 (95% CI 0.77–0.75, 0.85–0.87) good calibration; caveat, original model includes mild TBI patients
 TBI Mortality CRASH CT ↓ ROB: applicability [some mild TBI], self-fulfilling prophecy Moderate 14-day mortality: AUC 0.83 (0.78–0.87); good calibration; caveat, original model includes mild TBI patients
 TBI Mortality IMPACT Core ↓ of 7 papers high ROB due to small sample sizes, poor report on methods, variable outcome time points, self-fulfilling prophecy; remaining papers high quality Moderate 6-month mortality: AUC 0.66–0.9 (95% CI 0.8–0.86, 0.87–0.94), most papers report calibration
 TBI Mortality IMPACT extended ↓ of 7 papers high ROB due to small sample sizes, poor report on methods, variable outcome time points, self-fulfilling prophecy; remaining papers high quality Moderate 6-month mortality: AUC 0.71–0.85 (95% CI 0.76–0.81, 0.86–0.89)
 TBI Mortality IMPACT lab model ↓ two larger paper, two smaller papers, two with high ROB for participation, predictors, outcome, self-fulfilling prophecy) Moderate 6-month mortality: AUC 0.72–0.80 (95% CI 0.75–0.86)
 TBI Mortality Marshall CT ↓ high ROB (applicability, lack of calibration, outcome ROB, self-fulfilling prophecy) Moderate

6-month mortality: AUC 0.635- 0.819 (95% CI 0.769–0.869); calibration reported for one study

12-month mortality: AUC 0.61 (95% CI 0.57–0.65), calibration not reported

 TBI Mortality Rotterdam CT ↓ 4 papers, three with high ROB for applicability, sample size, analysis, 1/3 mild TBI, self-fulfilling prophecy) Low 6-month mortality: AUC 0.699–0.875 (95% CI not reported-0.814, not reported-0.936)
 TBI Mortality Helsinki CT ↓ both papers with high ROB for applicability, analysis, outcome, 1/3 mild TBI, self-fulfilling prophecy lack of calibration) Moderate

6-month mortality: AUC 0.744 (95% CI not reported); calibration not reported

12- month mortality: AUC 0.74 (95% CI 0.7–0.77); calibration not reported

 TBI Unfavorable functional outcome CRASH basic ↓ ROB (two of four studies with ROB for participation, applicability, self-fulfilling prophecy calibration not reported) Moderate 6-month AUC 0.8–0.86 (95% CI 0.75–0.88, 0.84–0.9)
 TBI Unfavorable functional outcome CRASH CT ↓ ROB (two studies, one with ROB for participation, applicability, self-fulfilling prophecy calibration not reported) Moderate 6-month AUC 0.86–0.89 95% CI (0.82–0.84, 0.89–0.93)
 TBI Unfavorable functional outcome IMPACT Core ↓ ROB (1 of 8 studies with ROB for participation, outcome, self-fulfilling prophecy, 2 for analysis, 2 without calibration, 1 with variable outcome time point assessment) Moderate 6-month AUC 0.71–0.87, 95% CI (0.76–0.81, 0.84–0.91)
 TBI Unfavorable functional outcome IMPACT extended ↓ ROB (1 of 6 studies with ROB for analysis, self-fulfilling prophecy, no calibration, 1 with variable outcome time point assessment) Moderate 6-month AUC 0.73–0.88 (95% CI 0.77–0.83, 0.86–0.93)
 TBI Unfavorable functional outcome IMPACT lab model ↓ ROB (self-fulfilling prophecy, 1 with variable outcome time point assessment, 1 of 4 studies with not enough information to judge ROB) Moderate 6-month AUC 0.75–0.87 (95% CI 0.82–0.92)
 TBI Unfavorable functional outcome Marshall CT ↓ ROB (participation [1/3–40% mild TBI], applicability, analysis, self-fulfilling prophecy) Low
