Fig. 5. Relationship between the value of the PHLF score and occurrence of PHLF in (A) development cohort, (B) internal validation cohort and (C) external validation cohort.

The horizontal dotted line indicates the cut-off value of the PHLF score (14.7) for the prediction of PHLF. Patients with PHLF score ≥14.7 belong to the high-risk group, otherwise patients were classified in the low-risk group. ^*p<0.05, ^**p<0.001, in comparison with the low-risk group.
