The choice of strain significantly affected the Infarct size coefficient of variation, so that the Wistar rendered lower variability than Sprague Dawley, which was chosen as the reference category. The Other strains category increased variability in comparison to Sprague Dawley. Regarding mortality rate, the effects of animal strain was limited to a slight decrease from using SHR. N = 469 and 351, respectively, in the two analyses/graphs. The bars represent 0.95 confidence intervals.
