Armstrong et al. conducted an initial systematic review and meta‐analysis of 24 observational studies published by 31 May 2020, which included 10,150 patients, finding that mortality was 41.6%, with evidence that this was decreasing as the pandemic progressed.

This new updated meta-analysis seems to show that any fall in mortality rate between June and September appears to have flattened or plateaued.
