Linear Regression Analysis and Bland–Altman Plot for T2* of IMH Determined Using ssT2* and aT2* < 20 ms. A Linear regression analysis in patients (left—acute; right—chronic) were strongly correlated but the absolute T2* values 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 (left—acute; middle—chronic; and right—ex-vivo) show similar strong regressions and highly discordance T2* values as evidenced by the lines of best fit having slopes < 1.0 (all p ≤ 0.001). 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
