Bland-Altman graphic demonstrating the reproducibility of circumferential strain. (A) Interobserver variability of circumferential strain at baseline. (B) Interobserver variability of circumferential strain during exercise testing. (C) Intraobserver variability of circumferential strain at baseline. (D) Intraobserver variability of circumferential strain during exercise testing. The blue dashed line indicates the mean bias (mean difference) and the red dashed lines represent the limits of agreement.
