Effect of stellate ganglion block on postoperative nausea and vomiting after general anesthesia: A meta-analysis.
Synthesis in The Journal of international medical research, 2025. 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
ObjectiveTo identify the effect of stellate ganglion block on the incidence of postoperative nausea and vomiting.MethodsWe systematically searched electronic databases for published randomized controlled trials comparing stellate ganglion block with placebo for reducing postoperative nausea and vomiting. The primary outcome was the incidence of postoperative nausea and vomiting after general anesthesia. Meta-regression analysis was performed to investigate potential sources of heterogeneity. Trial sequential analysis was also carried out to calculate the required information size.ResultsIn total, 16 randomized controlled trials including 1385 patients were included in the study. Stellate ganglion block significantly reduced the incidence of postoperative nausea and vomiting (relative risk, 0.59; 95% confidence interval, 0.49-0.70;
