When applying the BIRADS classification with the modification described above, a kappa coefficient of 0.60 (0.55-0.65, 95% confidence interval) and a quadratic weighted kappa of 0.66 (0.62-0.70, 95% confidence interval) were found.
Inter-rater reliability assessment was performed for 15 patients, giving an intra-class correlation coefficient of 0.96 (95% confidence intervals, 0.89 to 0.99).
For the 15 patients examined by both echocardiographers, inter-rater reliability assessment was performed, giving an intra-class correlation coefficient of 0.96 (95% confidence intervals, 0.89 to 0.99).
Modification of the slack test in vivo resulted in good reproducibility of V0, with an intraclass correlation coefficient of 0.87 (95% confidence interval: 0.68 0.95).
As shown in Fig. 5, test retest data of V0 measured at 15, 50, and 85%MVC appeared to be evenly distributed around the line of identity (y = x) with an intraclass correlation coefficient of 0.87 (95% confidence interval: 0.68 0.95).
