  1. Columns show how the total deaths during this period compare with the most probably excess deaths identified by univariate combination #2, multivariate combination #1, the overlap between these combinations, and the overlap between all 12 combinations. The underlying assumption is that the most probable excess deaths would occur on the hotter days
