COVID‐19 Mortality in Swedish Intensive Care Units: A Multicenter Survival Analysis
Authors' conclusion
Among patients admitted to ICU due to COVID-19, we observed a difference in mortality related to the hospital of first ICU admission. This difference persisted after adjustment for calendar time, baseline confounders, and healthcare county.
