Effect of Stellate Ganglion Block in Relieving Postoperative Pain After Surgery: A Systematic Review and Meta-Analysis.
Review in Journal of pain research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Postoperative acute pain is a common complication after surgery. Stellate ganglion block (SGB) has been reported to relieve pain, but evidence remains inconsistent. A prior meta-analysis had limitations, including unexplained heterogeneity and incomplete data. Therefore, we conducted this updated meta-analysis to evaluate the effectiveness of SGB in reducing postoperative pain in patients undergoing surgery under general anesthesia. Methods: We searched PubMed, EMBASE, Cochrane Library and Web of Science for randomized controlled trials (RCTs) comparing stellate ganglion block (SGB) with control (placebo or no treatment) in adults undergoing surgery under general anesthesia. According to the PICO framework: Population-adults under general anesthesia; Intervention-preoperative SGB; Comparison-control (placebo or no treatment); Outcome-postoperative pain scores. The GRADE methodology was utilized to appraise evidence quality. Mean differences (MD) or risk ratios (RR) were calculated using random-effects models. Results: Eight RCTs involving 562 patients were included. SGB reduced postoperative pain score at 6 hours (MD = -0.62; 95% CI: -0.92, -0.32, I Conclusion: Current evidence suggests that SGB may reduce early postoperative pain; however, the certainty of this evidence is very low.
