Other factors that showed associations in univariate analysis but did not reach statistical significance in multivariate analysis included atrial fibrillation (ORa=2.1; 95% CI: 0.8-5.4; p=0.128), renal insufficiency (ORa=1.8; 95% CI: 0.7-4.6; p=0.218), and NYHA functional class III-IV (ORa=2.3; 95% CI: 0.9-5.9; p=0.087).

Renal insufficiency showed a trend toward increased mortality risk (ORa=2.1; 95% CI: 0.5-8.7; p=0.298), as did NYHA functional class IV (ORa=2.8; 95% CI: 0.6-12.4; p=0.184), but neither achieved statistical significance, likely due to the relatively small number of mortality events (n=16) limiting statistical power.
