The presence of CLD was significantly associated with higher risk of postoperative bleeding (adjusted OR (aOR)=1.64, 95% CI 1.15 to 2.34, p=0.007). The presence of CLD (aOR=1.98, 95% CI 1.39 to 2.82, p&lt;0.001) and length of hospital stay (aOR=1.06, 95% CI 1.04 to 1.08, p&lt;0.001) were significantly associated with higher risk of in-hospital mortality.
