With respect to secondary outcomes, blood loss (WMD -69.16; 95% CI -101.72 to -36.61; P < 0.01), length of hospitalization (LOH) (WMD -2.65; 95% CI -3.41 to -1.89; P < 0.01), minor complication rate (OR 0.70; 95% CI 0.53 to 0.94; P = 0.02), postoperative liver failure (OR 0.60; 95% CI 0.38 to 0.95; P = 0.03), and postoperative ascites (OR 0.44; 95% CI 0.28 to 0.72; P < 0.01) was lower in LH than in OH. Here, PLOD1 is linked to Hepatic failure.
