In multivariable analyses, female sex, preoperative anemia, multilobar resections, as well as serum alanine-aminotransferase levels, thrombocyte counts and Rhesus negativity were identified as independent predictors of ABT, being associated with OR (95% Confidence interval, p-value) of 2.44 (1.23–4.88, p = 0.0112), 18.16 (8.73–37.78, p < 0.0001), 5.79 (2.50–13.38, p < 0.0001), 3.98 (1.73–9.16, p = 0.0012), 2.04 (1.04–4.02, p = 0.0390) and 2.84 (1.23–6.59, p = 0.0150), respectively. This evidence concerns the gene GPT and anemia.
