Figure 3From: Visually estimated ejection fraction by two dimensional and triplane echocardiography is closely correlated with quantitative ejection fraction by real-time three dimensional echocardiography Linear regression analysis of eyeballing two-dimensional echocardiography EF and quantitative three-dimensional echocardiography EF ( upper left ) and Bland-Altman analysis comparing two-dimensional echocardiography and quantitative three-dimensional echocardiography EF ( upper right ). Lines represent regression line (centre) and 95% CI for the mean (outer bounds). Linear regression of eyeballing triplane EF and three-dimensional echocardiography EF (lower left) and Bland-Altman analysis comparing eyeballing triplane EF and three-dimensional echocardiography EF (lower right).Back to article page
