1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

backgroundUltrasound-guided Erector Spinae Plane Block (ESPB) has been increasingly applied in patients for postoperative analgesia. Its effectiveness remain uncertain. This meta-analysis aimed to determine the clinical efficacy of ultrasound-guided ESPB in adults undergoing general anesthesia (GA) surgeries.

methodsA systematic databases search was conducted in PubMed, Embase, and the Cochrane Library for randomized controlled trials (RCTs) comparing ESPB with control or placebo. Primary outcome was iv. opioid consumption 24 h after surgery. Standardized mean differences (SMDs) and risk ratios (RRs) with 95% confidence intervals (CIs) were calculated with a random-effects model.

resultsA total of 12 RCTs consisting of 590 patients were included. Ultrasound-guided ESPB showed a reduction of intravenous opioid consumption 24 h after surgery (SMD = - 2.18; 95% confidence interval (CI) -2.76 to - 1.61,p < 0.00001). Considerable heterogeneity was observed (87%). It further reduced the number of patients who required postoperative analgesia (RR = 0.41,95% CI 0.25 to 0.66,p = 0,0002) and prolonged time to first rescue analgesia (SMD = 4.56,95% CI 1.89 to 7.22, p = 0.0008).

conclusionsUltrasound-guided ESPB provides effective postoperative analgesic in adults undergoing GA surgeries.
