‡ TAPSE-slope(cm/s) = TAPSE (cm) *1000/ TAPSE-t (msec).
For reliability analysis, we calculated the inter-class correlation
coefficient (ICC) between 84 TAPSE-t readings by two other
cardiologists. In IBM SPSS statistics 24, ICC type C was calculated
between these three raters, which was 0.886 (95% CI: 0.82-0.92).
Grouped scatter plot of three times TAPSE-t measurement by three raters
is shown in figure 2.
