Abbreviations: AMI, acute myocardial infarction; ANOVA, analysis of variance; Circ., diseases of the circulatory system; HF/CHF, heart failure or congestive heart failure; IHD, ischemic heart disease.

^aThe analysis group thus includes the day of the Super Bowl (January 22, 1984), and the 14 days after the Super Bowl (January 22, 1984–February 5, 1984, 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.
