Bland–Altman plots for the interobserver-acquisition variability (first reader and first acquisition vs second reader second acquisition) for dimension (A), area (B), and volume (C) measurements. 2D indicates 2 dimensional; 2-F, Fractional Area Change in apical 2 chamber view; 4-F, Fractional Area Change in apical 4 chamber view; 5/6 AL, 5/6 area-length method; EDD, end-diastolic dimension; EDPW, end-diastolic posterior wall; EDV, end-diastolic volume; EF, ejection fraction; FAC, fractional area change; PSX, parasternal; and SF, shortening fraction.
