Table 2.
Comparison of incidence of primary ED diagnosis by CCSR diagnosis categories between periods. N represents the raw number of cases in each period. The difference % compares the raw number of cases between the baseline and early pandemic periods. Incidence is the number of a given case-type per 100 ED encounters. IRR = Incidence Rate Ratio, which is the ratio of incidences between the two periods. Note that the confidence intervals refer only to the IRR, and do not relate to the change in total number of cases in a given category
