Univariable and multivariable competing risk regression analysis for mortality, including age, aetiological cure of liver disease, inclusion time, MELD, and albumin in the study cohort (model 1), grade 2 ascites (model 2), and grade 3 ascites (model 3). Values in bold denote statistical significance.
aSHR, adjusted subdistribution hazard ratio; MELD, model for end-stage liver disease; SHR, subdistribution hazard ratio.
