Figure 1

Box plots showing the variability in the mean amount of scar in grams depending on the quantitative method used according to the scar pattern: ischemic (A) and non-ischemic (B). The p-values were derived from the t-test for differences in mean amount of scar between each automatic method and the semi-automated technique. In the ischemic group (A) BCT, FWHM and 8SD were not significantly different from the SA, while in the non-ischemic group (B), only BCT and 8SD did not differ statistically from the SA. SA = semi-automated; BCT = background correction technique; FWHM = full width at half maximum; SD = standard deviation
