This article seems to better explain the BMJ reference, at least it has more details: https://www.medicalnewstoday.com/articles/1-in-3-excess-deat...

"Healthcare disruption and emotional crises may have led to around a third of the 225,530 “excess deaths” in the United States between March 1 and August 1, 2020, a new study suggests."

Is it likely that 215,000 died from coronavirus, like Nature said? I'd like to see the math behind that.
