Risk factors for postoperative nausea and vomiting after general anesthesia: a systematic review and meta-analysis.
Synthesis in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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: This systematic review and meta-analysis aimed to quantitatively analyze and summarize the risk factors of postoperative nausea and vomiting (PONV) in patients undergoing general anesthesia. Methods: Literature screening, data extraction, and statistical analysis were conducted by an independent investigator. Meta-analyses were conducted for included studies using a random-effects method and generic inverse variance. All risk factors analyzed in the multifactorial regression models of the included studies were included in the meta-analysis to calculate the combined OR and 95% CI. Results: We included 31 studies ( Conclusion: This study revealed patient-related, procedure-related, and anesthesia-related significant risk factors for PONV. This may provide a basis for clinical prevention, but a rigorously designed prospective study should be performed to confirm the findings of this study.
