1 Continuous association: Pearson if both variables pass Shapiro-Wilk; otherwise Spearman. Binary rows: t-test if residual normality and Levene are adequate; otherwise Wilcoxon rank-sum.
2 Group comparison: continuous variables use ANOVA if residual normality and variance homogeneity hold; otherwise Kruskal-Wallis. Binary variables use chi-squared when expected counts are adequate; otherwise Fisher exact.

6.1 Figure 1. Study flowchart

The diagram describes the protocol used for the enrollment of patients in the present study. LS = Liver Stiffness; T-TEER = Tricuspid Transcatheter Edge-to-Edge Repair.

6.2 Figure 2. Liver stiffness assessed by elastography

A liver portion free of large vessels should be selected, and 10 measurements should be performed. The representative value is the median of these measurements, which is considered reliable if the IQR/median ratio is less than 30%.

Comparison of tricuspid regurgitation severity at baseline, 1 month and 12 months of follow-up. Boxed labels indicate the percentage of subjects with moderate or less TR.

Esta figura indica algo muy parecido a la anterior, pero con contrastes sobre la proporción de transiciones, la figura anterior es útil a nivel exploratorio, pero los p valores son pobres y el contraste global de Q de Cochran no sale significativo, hay que decidir si merece más la pena mostrar el gráfico de transiciones que os pongo aquí abajo.

6.6 Figure 5. Individual trajectories of LS over time

This graphic shows the evolution of LS of each individual subject. It suggests heterogeneous responses, with several patients showing reductions over time and others remaining stable or increasing modestly.

6.7 Figure 6. Baseline LS and follow-up LS

Scatterplot showing the relationship between baseline LS and LS change at 1 month and 12 months. The y-axis represents follow-up LS minus baseline LS; values below zero indicate LS reduction. Smoothed curves display the association between baseline LS and change in LS. Boxed labels show paired t-test statistics and Holm-adjusted p values.

6.8 Figure 7. Functional class according to NYHA classification

Functional class according to NYHA classification at baseline, 1 month and 12 months of follow-up. Boxed labels indicate the percentage of subjects in NYHA class I/II.
