| HR (95% CI) | P value | HR (95% CI) | P value | HR (95% CI) | P value | |
| Unadjusted | 2.1 (1.4–3.3) | .001 | 3.6 (1.7–7.7) | .001 | 1.9 (0.9–4.1) | .119 |
| Multivariable adjusted† | 1.9 (1.2–3.0) | .004 | 3.1 (1.4–7.0) | .007 | 1.7 0.8–3.9) | .190 |
All models are weighted for the stratified sampling. Age was used as time scale.
Reference category: lower quartiles (1–3) of PVCs.
CI = confidence interval; HR = hazard ratio; PVC = premature ventricular complex.
