  1. Before propensity score matching, there were significant differences between the two groups in the location related to massive vessels, tumor distribution, radiographic tumor size, and tumor number between group E (n = 163) and group LR (n = 110). After matching, the four baseline variables were balanced (P > 0.05)
  2. LR Liver resection, EN Enucleation, BMI Body mass index
  3. *P < 0.05 was considered significant difference
