The relationship between patient-reported hunger and gastric contents in adult patients with acute surgical abdominal pathology: exploratory prospective observational study.
Article in BJA open, 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: Patient-reported hunger has been used to infer an empty stomach preoperatively. We hypothesised that hungry patients with acute abdominal pathology would be considered 'low risk' of aspiration when assessed by gastric ultrasound. The primary aim was to determine whether patient-reported hunger was associated with gastric ultrasound findings of aspiration risk in patients with acute abdominal pathology. Methods: In this exploratory prospective observational study, we recruited adults awaiting emergency abdominal surgery without additional risk factors for gastroparesis. Participants self-completed a questionnaire, and then a blinded operator performed a standardised gastric ultrasound. Hunger was assessed using three question formats (binary, ordinal, or numerical rating scale). A 'high risk' stomach was defined as the presence of gastric solids, Perlas grade 2, cross-sectional area >9.9 cm Results: One hundred patients were enrolled (median age=32 years, 61% female, mean BMI=28 kg m Conclusions: In this exploratory study, no meaningful relationship between hunger and aspiration risk using gastric ultrasound could be identified. Our results require confirmation.
