Perineural Dexamethasone to Improve Postoperative Analgesia with Peripheral Nerve Blocks: A Meta-Analysis of Randomized Controlled Trials

Figure 2

Pooled data evaluating the effect of perineural dexamethasone on analgesia duration compared to control. Data evaluated using a random effects model. Point estimate (99% CI) for overall effect was 473 (264 to 682) minutes. Weighted mean difference for individual study represented by square on forest plot with 99% confidence interval of the difference shown as solid line. Larger sized square and thicker 99% confidence interval line denote larger sample size. The diamond represents the pooled estimate and uncertainty for the effects of perineural dexamethasone compared to control.
