A: Forest plots of the meta-analysis of the albumin level; B: Forest plots of subgroup analysis of the albumin level (studies with a total number of patients less than 50 were excluded); C: Forest plots of subgroup analysis of the albumin level (studies with treatment duration greater than 3 mo were excluded); D: Forest plots of subgroup analysis of the albumin level (among the included studies, the majority of patients had Child grade A or B and treatment duration was greater than 3 mo).
