Nonselective beta-blockers in cirrhotic patients with no or small varices: A meta-analysis

To explore effects of nonselective beta-blockers (NSBBs) in cirrhotic patients with no or small varices.

The PubMed, EMBASE, Science Direct, and Cochrane library databases were searched for relevant papers. A meta-analysis was performed using ORs with 95%CI as the effect sizes. Subgroup analysis was conducted according to the studies including patients without varices and those with small varices.

Overall, 784 papers were initially retrieved from the database searches, of which six randomized controlled trials were included in the meta-analysis. The incidences of large varices development (OR = 1.05, 95%CI: 0.25-4.36; P = 0.95), first upper gastrointestinal bleeding (OR = 0.59, 95%CI: 0.24-1.47; P = 0.26), and death (OR = 0.70, 95%CI: 0.45-1.10; P = 0.12) were similar between NSBB and placebo groups. However, the incidence of adverse events was significantly higher in the NSBB group compared with the placebo group (OR = 3.47, 95%CI: 1.45-8.33; P = 0.005). The results of subgroup analyses were similar to those of overall analyses.

The results of this meta-analysis indicate that NSBBs should not be recommended for cirrhotic patients with no or small varices.
