Fig. 2From: Improving ultrasound-based prostate volume estimationBland-Altman plots for outlier removal when using (a) the new formula with 0.66 as a coefficient and (b) the ellipsoid formula. Linear regression analyses of estimated vs. measured prostate volumes using (c) the new formula with 0.66 as a coefficient, after outlier removal and (d) the ellipsoid formula, after outlier removal. In (c) and (d), solid line represents the linear regression with a constant term. Dashed line represents the linear regression passing through the interceptBack to article page
