Table 5 Results of sensitivity analyses of in-hospital mortality between patients in resource-rich ICUs versus HDUs, standard ICUs versus HDUs, and resource-rich ICUs versus standard ICUs

From: Intensive care unit versus high-dependency care unit for patients with acute heart failure: a nationwide propensity score-matched cohort study
