Survival curves for the five COVID-19 outbreaks to date. A Survival curve of patients receiving mechanical ventilation, showing gradual improvement in survival from the first outbreak to the fifth outbreak. In the post hoc analysis, there was a significant difference between the first and fourth outbreaks (p = 0.033) and between the third and fourth outbreaks (p = 0.001). There was also a significant difference between the fifth outbreak and all other outbreaks (all p < 0.001). B Survival curve of patients receiving ECMO, showing that the survival rate remained nearly the same from the first outbreak to the fifth outbreak. COVID-19, coronavirus disease 2019; ECMO, extracorporeal membrane oxygenation
