The proportion of all-cause mortality during the admission was 0.068 (0.0485-0.0947) for the CHF-positive cohort (32 admissions out of the 470 admission cohort) while it was 0.0297 (0.0176 - 0.0497) for the CHF-negative cohort (14 admissions out of the 470 admission cohort): the mortality was higher in the CHF cohort (6.8% vs 2.97%), but the difference did not reach statistical significance.
