Table 5.
A propensity score analysis for moderate or severe PVL 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) |
|---|---|---|---|---|---|---|
| Moderate or severe PVL | 1.0 | 1.9 | −0.9 (−3.6 to 1.8) | 0.5 | 1.3 | −0.8 (−2.7 to 1.2) |
ATE, average treatment effect; ATT, average treatment effect on the treated; CAV, commercially available valve; PS-SM ATE, propensity score stratified mean average treatment effect
PVL, paravalvular leak.
a
Event rates are expressed as propensity score stratified mean average treatment effect (PS-SM ATE) rates across quintiles and average treatment effect (ATE)-adjusted difference.
b
Event rates are expressed as propensity score stratified mean ATE on the treated (PS-SM ATT) rates across quintiles and ATT-adjusted difference.
