Description of intervention(s) / exposure
From January 2015 to December 2019, patients who received open liver surgery would receive three different types of analgesic modalities to control postoperative pain, namely intravenous patient controlled analgesia (IV-PCA) only, IV-PCA + nerve blocks and patient controlled epidural analgesia (PCEA) for 3 days. Over the three day period, PCA infusion and bolus dose would be adjusted according to patients' pain level and side effects daily and as requested by patient. The total opioid requirement wouuld be recorded at the end of day 3.
Opioid-related side effects, removal of nasogastric tube and urinary catheter, initiation of bowel movement and the length of hospital stay would also be recorded before patient discharge.

Statistical methods / analysis
The statistical information including patient general data, clinical indicators, and perioperative index were collected accurately. Data were analyzed statistically using SPSS Version 25 and R software. The data were presented by mean±standard error of mean (Mean ± SEM), and categorical variables as percentages. Continuous data was compared using the Analysis of variance (ANOVA) and Tukey HSD for further post-hoc analysis. Data were further adjusted for major resection, HCV infection, albumin and hemoglobin using PROC GLM procedure. Proportions were compared using Chi-square test. For all statistical tests, P value < 0.05 was considered to be statistically significant.
