Multivariate competing risk regression for time to ELA
| Variable | ELA (95% CI) | P value |
|---|---|---|
| Primary device type (pacemaker vs ICD) | 0.964 (0.554–1.679) | .8972 |
| Sex (female vs male) | 1.052 (0.731–1.516) | .7841 |
| Age (by decile) | 0.915 (0.764–1.097) | .3367 |
| Lead chamber (RA vs RV) | 1.683 (1.061–2.670) | .0270 |
| Lead manufacturer (Abbott vs Medtronic) | 10.443 (5.151, 21.170) | <.001 |
| Lead French size (by 1 unit) | 0.955 (0.641–1.423) | .8199 |
| Lead access | .7131∗ | |
| Cephalic vs other | 0.808 (0.325–2.010) | .6467 |
| Subclavian vs other | 0.874 (0.357–2.801) | .7682 |
| Cephalic vs subclavian | 0.924 (0.639–1.338) | .6775 |
CI = confidence interval; ELA = electrical lead abnormality; ICD = implantable cardioverter-defibrillator; RA = right atrium; RV = right ventricle.
