^aThe analysis group thus includes the day of the Super Bowl (January 20, 1980), and the 14 days after the Super Bowl (January 20, 1980–February 3, 1980, 15 days total).

^bTo remove the impact of the known peak in cardiac death rates around the holidays, the analysis excludes data from January 1 to 14 (14 days starting with New Year's Day).

^cRates expressed per day per 100 000 population (using total deaths and average population).

^dEstimated from a 1‐way ANOVA with Super Bowl Day as the only factor.

^eFor the Super Bowl effect.
