Linear Regression Analysis and Bland–Altman Plot for IMH Volume Determined Using ssT2* and aT2* < 20 ms. A Linear regression analysis in patients (left—acute; right—chronic MI) were strongly correlated but the IMH volumes deviated significantly (slopes < 1.0, both p < 0.001), which was also shown by Bland–Altman plot (B). C Linear regression analysis in animals at acute MI (left—acute; middle—chronic; and right—ex-vivo) show similar strong regressions and highly discordance IMH volumes as evidenced by the lines of best fit having slopes < 1.0 (all p < 0.05). D shows Bland–Altman plot. The black solid lines denote the 95% confidence bands, and for reference the dotted line denoting the line of identify is shown
