A propensity score analysis for mortality and disabling stroke at 1 y.
| Event | Global FlexNav (n = 193): PS-SM ATE ratea | CAV (n = 362): PS-SM ATE ratea | ATE adjusted differencea (95% CI) | Global FlexNav (n = 193): PS-SM ATT rateb | CAV (n = 362): PS-SM ATT rateb | ATT adjusted differenceb (95% CI) |
|---|---|---|---|---|---|---|
| Composite end point of mortality or disabling stroke | 5.0 | 13.9 | −8.9 (−14 to −3.7) | 6.2 | 15.3 | −9.1 (−15.4 to −2.7) |
| Mortality | 3.3 | 12.7 | −9.4 (−13.7 to −5.1) | 5.2 | 14.5 | −9.3 (−15.5 to −3.1) |
| Disabling stroke | 2.6 | 2.5 | 0.1 (−3.4 to 3.6) | 2.1 | 2.4 | −0.3 (−3.5 to 2.8) |
ATE, average treatment effect; PS-SM ATE, propensity score stratified mean average treatment effect
Values given are percentages.
a
Event rates are expressed as PS-SM ATE rates across quintiles and ATE-adjusted difference.
b
Event rates are expressed as propensity score stratified mean ATE on the treated (PS-SM ATT) rates across quintiles and ATE on the treated (ATT)-adjusted difference.
