Data are given as number (%)
The conventional group was composed of the right lobe, extended right lobe, left lobe, extended left lobe, and left lateral segment grafts. The unusual group was composed of the right anterior section, right posterior section, or extended left liver plus caudate lobe
^†p values were calculated according to graft types of right lobe (Rt. conventional vs. RAG + RPG) using Fisher’s exact test
^‡p values were calculated according to graft types of left lobe (Lt. conventional vs. Ext. LLC) using Fisher’s exact test
^*p values of the conventional graft versus the unusual graft comparisons were calculated using Fisher’s exact test
Ext. LLC, extended left liver plus caudate lobe graft; RAG, right anterior section graft; RPG, right posterior section graft
