Assessment of residual gastric volume by ultrasound prior to upper endoscopy: a prospective cohort study.
Article in Canadian journal of anaesthesia = Journal canadien d'anesthesie, 2025. 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
purposePulmonary aspiration is an adverse event with high morbidity and mortality. Despite fasting for > 8 hr, some patients still have residual gastric volume and are thus at risk of aspiration. We aimed to determine the accuracy of gastric ultrasound in assessing residual gastric content in patients undergoing upper gastrointestinal endoscopy.
methodsIn a prospective cohort study, we performed gastric ultrasound immediately before upper gastrointestinal endoscopy in a sample of 294 patients. We categorized the ultrasound results as high risk of aspiration when the fluid volume was > 1.5 mL·kg
resultsWe included 282 patients in the analysis. The incidence of residual gastric contents was 5%. There were no aspiration events. Prokinetic use (relative risk [RR], 7.5; 95% confidence interval [CI], 1.9 to 29.1; P < 0.01), previous stroke (RR, 4.0; 95% CI, 1.2 to 13.6; P = 0.02), and male sex (RR, 3.3; 95% CI, 1.2 to 9.4; P = 0.02) were significantly more frequent among those with residual gastric content. The ultrasonography's specificity and sensitivity to predict gastric content at risk of aspiration were 100% and 77%, respectively, with a positive predictive value of 100% and a negative predictive value of 99%.
conclusionUltrasonography was an effective way to assess residual gastric content, which can help improve patient safety.
