Summary of deaths by day of the 2009 hot weather event
| Date, 2009 | Daily maximum temperature at Vancouver International Airport (°C) | Total deaths (%) | Uni. #2 probable excess deaths (%) | Multi. #1 probable excess deaths (%) | Overlap between uni. #2 and multi. #1 (%) | Overlap between all combinations (%) |
|---|---|---|---|---|---|---|
| N = 411 | N = 114 | N = 114 | N = 72 | N = 30 | ||
| July 27 | 27.8 | 11.2 | 9.6 | 9.6 | 9.7 | 6.7 |
| July 28 | 30.9 | 12.7 | 7.9 | 10.5 | 8.3 | 10.0 |
| July 29 | 34.0 | 15.2 | 15.8 | 18.4 | 16.7 | 20.0 |
| July 30 | 34.4 | 18.4 | 18.4 | 18.4 | 22.2 | 23.3 |
| July 31 | 28.7 | 15.6 | 21.1 | 17.5 | 18.1 | 20.0 |
| August 1 | 26.7 | 11.2 | 11.4 | 11.4 | 9.7 | 10.0 |
| August 2 | 25.5 | 15.1 | 15.8 | 14.0 | 15.3 | 10.0 |
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
