The efficacy of transcutaneous electrical acupoint stimulation on postoperative nausea and vomiting after laparoscopic surgery: a meta-analysis of randomized controlled trials.
Synthesis in Frontiers in medicine, 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
Background: Postoperative nausea and vomiting (PONV) is a common complication after laparoscopic surgery, which may cause fluid and electrolyte imbalance and delay postoperative recovery. Pharmacological interventions are only partially effective and have adverse effects. This study aimed to systematically evaluate the efficacy of transcutaneous electrical acupoint stimulation (TEAS) in managing PONV after laparoscopic surgery. Methods: We systematically review Cochrane Library, PubMed, Embase and Web of Science for randomized controlled trials (RCTs). Two investigators independently conducted study selection, data extraction, and bias assessment using the Cochrane Risk of Bias Tool. Meta-analyses were performed in RevMan 5.4 and heterogeneity was assessed using Results: Nine RCTs involving 2,550 participants (1,272 in the TEAS group and 1,278 in the control group) were analyzed. TEAS significantly reduced PONV incidence [ Conclusions: Our findings suggest that TEAS may be an effective adjunctive non-pharmacological treatment for PONV in patients undergoing laparoscopic surgery. When used in combination with standard antiemetic prophylaxis, TEAS can further reduce the incidence of nausea and vomiting, decrease the need for rescue antiemetics, and shorten the time to first flatus, thereby demonstrating significant added value in facilitating postoperative recovery.
