"Our estimate of the average treatment effect across the 18 events implies that they increased subsequent confirmed cases of Covid-19 by more than 250 per 100,000 residents. Extrapolating this figure to the entire sample, we conclude that these 18 rallies ultimately resulted in more than 30,000 incremental confirmed cases of Covid-19. Applying county-specific post-event death rates, we conclude that the rallies likely led to more than 700 deaths (not necessarily among attendees)"
