case_images: A single focal window of 14 days prior to the date of MI, and 100 referent windows of the same length were defined, as illustrated in Figure 1.

case_images: An example of the SCCS is provided in Box 3, and the design is illustrated in Figure 3. The first 4 days after vaccination was considered as a transition window (induction window) (as development of the outcome was considered biologically impossible), and the 28 days before vaccination was used as another transition window (pre-exposure window) (Figure 3).
