Forest plot depicting A) 0–24 hour and B) 24–48 hour analgesic consumption. The individual trials' weighted mean differences,standard error, and the pooled estimates of the ratio of means are shown. The 95% confidence intervals are shown as lines for individual studies and as diamonds for pooled estimates. Abbreviations: CISB, continuous interscalene block; SISB, single injection interscalene block.

Plot of the weighed mean difference of the rest pain visual analog scale (VAS) scores between the interventions over time. Error bars represent 95% confidence intervals; confidence intervals crossing zero (red line) indicate lack of statistical significance. Abbreviations: CISB, continuous interscalene block; SISB, single injection interscalene block. (*) P<0.05.
