Stroke Outcomes and Health State Utilities
| Stroke Outcome | LAAC, % | Warfarin, % | NOAC, % | Utility Value |
|---|---|---|---|---|
| Nondisabling stroke (MRS 0–2) | 75.010 | 24.016, 17, 40, 41 | 44.04, 6 | 0.76035 |
| Moderately disabling stroke (MRS 3) | 2.810 | 29.016, 17, 40, 41 | 21.4a | 0.39035 |
| Severely disabling stroke (MRS 4–5) | 16.710 | 35.016, 17, 40, 41 | 25.8a | 0.11035 |
| Fatal stroke (MRS 6) | 5.610 | 12.016, 17, 40, 41 | 8.8a | 0.000 |
LAAC indicates left atrial appendage closure; MRS, modified Rankin score; NOAC, nonwarfarin oral anticoagulant.

NOAC stroke outcomes were assumed to have the same distribution as warfarin across MRS 3 to 6.
