Risk of occurrence of STEMI during influenza season compared to
non-influenza season:
We compared proportion of STEMI over NSTEMI among all AMI cases between
influenza and non-influenza seasons. The purpose was to examine if
exposure to influenza season as opposed non-influenza season had any
significant impact on the frequency of events of STEMI compared to that
of NSTEMI. Univariate and multivariate Log binomial regression analyses
were performed to measure the unadjusted and adjusted RRs of occurrence
of STEMI during influenza vs. non-influenza season. The steps for
building the multivariate regression model followed the previously
mentioned process.
