The cut-off value for recurrence-free survival of (a) albumin (≤38.0 was the low-level group, >38.0 was the high-level group), (b) creatinine (≤58.0 was the low-level group, >58.0 was the high-level group), (c) direct bilirubin (≤2.9 was the low-level group, >2.9 was the high-level group), (d) lactate dehydrogenase (≤198 was the low-level group, >198 was the high-level group), (e) uric acid (≤325 was the low-level group, >325 was the high-level group), and (f) total bilirubin (≤7.9 was the low-level group, >7.9 was the high-level group) counted by X-tile. The blue color represents the samples of the low-level group and their survival, respectively. And the grey color represents the samples of the high-level group and their survival, respectively.
