Hazard ratios (CI) are for 1 unit increase in factor. Any factor not listed above was not significant at p≤0.05 in any model. Grey spaces indicate factors consistently associated with the outcome after all adjustments. Blank spaces indicate that the factor was not significant at p≤0.05 in that model.
Adjusted for age, gender, race, geographic region, LVEF, BUN, presence of severe mitral regurgitation, medications, symptom scores, and measures from the baseline CPX test
