Sensitivity Analysis: Adjusted HRs for Ventricular Tachycardia, Using an Intent-to-Treat Approach, Among Patients Having 2 Years of Observations
| Group | Comparison | HR (95% CI) |
|---|---|---|
| Ventricular tachycardia | ||
| HFrEF | HFrEF vs no HF | 7.13 (6.18-8.22) |
| HFpEF | HFpEF vs no HF | 1.98 (1.68-2.33) |
| Taking D or S | Taking D or S vs not taking D or S | 2.51 (1.88-3.36) |
| HFrEF taking D or S | HFrEF taking D or S vs HFrEF not taking D or S | 1.39 (0.91-2.11) |
| HFpEF taking D or S | HFpEF taking D or S vs HFpEF not taking D or S | 1.99 (0.91-4.36) |
| Sudden cardiac arrest | ||
| HFrEF | HFrEF vs no HF | 5.29 (4.01-6.98) |
| HFpEF | HFpEF vs no HF | 2.35 (1.68-3.29) |
| Taking D or S | Taking D or S vs not taking D or S | 1.47 (0.68-3.22) |
| HFrEF taking D or S | HFrEF taking D or S vs HFrEF not taking D or S | 2.58 (0.81-8.18) |
| HFpEF taking D or S | HFpEF taking D or S vs HFpEF not taking D or S | 0.56 (0.15-2.14) |
The multinomial propensity score method was used to select potential covariates (listed in Supplemental Tables 11 and 12), and any characteristics with SMDs larger than 0.1 (listed in Supplemental Tables 11 and 12) were incorporated into the final model for double adjustment. The inverse probability of treatment weighting was used to stabilize the covariates-induced differences and survival analysis for the recurrent events model was performed. HFrEF, HFpEF, and taking D or S are the main effects, and HFrEF taking D or S and HFpEF taking D or S are the interaction terms in the model.
