The effect of aromatherapy on postoperative nausea and vomiting: a systematic review and meta-analysis.
Article in Annals of medicine and surgery (2012), 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: To systematically evaluate the effect of aromatherapy on postoperative nausea and vomiting (PONV). Methods: Randomized controlled trials on aromatherapy for PONV were identified through searches of PubMed, Cochrane Library, Web of Science, Embase, ClinicalTrials, and Scopus from inception until October 2025. Meta-analysis was performed using RevMan Web and Stata 18. Results: Thirteen RCTs involving 1294 patients were included, with 661 patients in the aromatherapy group and 633 in the control group. The meta-analysis showed that, compared with the control group, the aromatherapy group had significantly reduced nausea severity measured by VAS within 24 h postoperatively (MD = -1.02, 95% CI: -1.60 to -0.45, Conclusion: Aromatherapy demonstrates favorable clinical efficacy in alleviating PONV. No serious adverse events were reported in the included studies; however, safety outcomes were not systematically assessed, and further research is warranted.
