ALB and atrioventricular block: In the subgroup analysis, when considering patients treated with elective TIPS either for ascites (n = 80) or another cause (AVB or before surgery, n = 26), we did not find any significant differences regarding baseline characteristics (Table S1) except regarding baseline serum sodium and albumin, which were lower in the subgroup of patients receiving TIPS for ascites or hydrothorax (p <0.001).
