Factors that were evaluated in univariate analysis were 99mTc-mebrofenin uptake, age, sex, diagnosis, chronic liver disease, resection type, operation time, blood loss, preoperative aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, albumin, bilirubin, alkaline phosphatase, γ-glutamyl transferase, prothrombin time, activated partial thromboplastin time, antithrombin III, and ICG clearance rate. Only significant factors in univariate analysis are shown.
