Correlations between tenting volume index and other morphological variables
A mild relationship was observed between TVi and 3D VCA (r= 0.56, P< 0.001) (Figure 3B). The correlations between TVi and PVi were negative and significant (r = -0.319, p = 0.0017), while AAi (r = 0.459, p < 0.001) correlated positively and significantly with TVi.
NT-proBNP also mildly correlated with TVi (r = 0.387, p < 0.001) (Figure 3A), whereas no significant association was found between NT-proBNP and PVi (P = 0.648).
ROC analysis showed that a 3D VCA ≥0.55 cm2 was the optimal cutoff point for predicting the occurrence of MVPt+ (area under curve 0.82; 95% CI, 0.74-0.91; P < 0.001) with a sensitivity of 98% and specificity of 57% (Figure 3C).
