Mortality at 90-days, 1-Year and 5-years
The overall rates of mortality for the study population were 5.6% (n=989), 8.7% (n=1,529), and 16 % (n=2,810) at 90-days, 1 and 5-years from the OHT, respectively. No differences in the center-level mortality rates at 90-days (5.8% vs 5.2% vs 5.9%, p=0.1), 1 year (8.8% vs 8.4% vs 9.0%, p=0.5) or at 5 years (16.2% vs 15.4% vs 16.5%, p=0.2) were observed between the low, intermediate and high terciles groups. In risk-adjusted Cox regression analysis demonstrated a 13% reduction in the hazard of death at 90 days (HR 0.87, 95% CI 0.77-0.99; p=0.04) in patients who received induction therapy, a relationship that was not appreciated at longer follow-up times (Supplementary Table 2).
