  • Listed are the baseline characteristics of the overall cohort and unadjusted hazard regression analysis for in-hospital mortality after HFH, with corresponding 95% CI and p values. Centre volume expressed in thousands with median (first and third quartiles: Q1–Q3).

  • APR, all patient refined; HFH, heart failure hospitalisation.
