Evaluation of performance (C-statistic (95% CIs)) of the GARFIELD-AF risk models (full and simplified) in predicting all-cause mortality in patients enrolled in ORBIT-AF (overall and stratified with and without OAC treatment)
| GARFIELD-AF Full risk model | GARFIELD-AF Simplified risk model | |
| 1-year mortality | 0.75 (0.73 to 0.77) | 0.75 (0.73 to 0.77) |
| Anticoagulant treated | 0.74 (0.72 to 0.77) | 0.74 (0.71 to 0.76) |
| Anticoagulant untreated | 0.77 (0.73 to 0.80) | 0.76 (0.72 to 0.79) |
| 3-year mortality | 0.74 (0.73 to 0.76) | 0.74 (0.73 to 0.75) |
| Anticoagulant treated | 0.73 (0.72 to 0.75) | 0.73 (0.71 to 0.75) |
| Anticoagulant untreated | 0.76 (0.73 to 0.78) | 0.76 (0.74 to 0.78) |
