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

Figure 2 Biliary strictures. A: In the period from 1995 to 2010, odds ratio (OR) for biliary strictures between “T-tube” group and “without T-tube” group was calculated with a fixed-effects model. The shape of diamond represents the overall effect of OR with 95% confidence interval (CI). The use of T-tube decreased the incidence of biliary strictures; B: In the period from 2010 to 2020, OR for biliary strictures between “T-tube” group and “without T-tube” group was calculated with a random-effects model. The shape of diamond represents the overall effect of OR with 95%CI. There was no significant difference between the two groups. OR: Odds ratio; CI: Confidence interval.
