T-tube vs no T-tube for biliary tract reconstruction in adult orthotopic liver transplantation: An updated systematic review and meta-analysis

Figure 4 Bile leaks. A: In the period from 1995 to 2010, odds ratio (OR) for peritonitis between “T-tube” group and “without T-tube” group was calculated with the fixed model. The shape of diamond represents the overall effect of OR with 95% confidence interval (CI). There was no significant difference between the two groups; B: In the period from 2010 to 2020, OR for peritonitis between “T-tube” group and “without T-tube” group was calculated with the fixed model. The shape of diamond represents the overall effect of OR with 95%CI. The incidence rate of bile leaks was significantly higher in “T-tube” group. OR: Odds ratio; CI: Confidence interval.
