After adjusting for organ dysfunction scores and premorbid conditions, we found that younger age, absence of frailty and the use of non-invasive respiratory support (NIRS) as first support strategy were independently associated with improved survival (hazard ratio for NIRS first [95% confidence interval], 0.59 [0.54-0.65], p 0.001). Age and mortality rates have declined over the first 8months of the pandemic. The use of NIRS as the first respiratory support measure was associated with survival, but causal inference is limited b
