As shown in Figure 2 a, the absolute Fat-LA volume measured and the overall ROI volume traced were significantly and directly correlated, with r = 0.531 (95% CI 0.404 to 0.638), p < 0.0001, while the Fat-LA density was instead only mildly correlated with the ROI volume drawn, with r = 0.208 (95% CI 0.047 to 0.358) and a borderline significance of p = 0.01 (not shown).
