The effect of liberal fluid fasting on gastric fluid volume in patients undergoing painless gastroscopy: a randomized controlled study.
Article in American journal of translational research, 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
objectiveThis study assessed the impact of liberalized clear liquid intake on gastric fluid volume (GFV) in patients undergoing painless gastroscopy.
methods184 patients scheduled for elective sedation gastroscopy underwent 1:1 randomization to a liberal fasting group (n = 92) or a conventional fasting group (n = 92). The liberal protocol permitted clear liquid consumption (≤150 mL/h) until 30 minutes pre-procedure, whereas the conventional group maintained standard preoperative 2-hour fasting. GFV quantification was performed through dual-modality assessment (gastric ultrasound and endoscopic aspiration). The primary endpoint was GFV, with secondary outcomes comprising fasting duration modifications, protocol satisfaction, adverse event incidence, and inter-method agreement.
resultsNo significant GFV differences emerged between groups as demonstrated by ultrasound or endoscopy. The liberal group demonstrated substantially shorter fasting durations and higher satisfaction scores, with comparable adverse event rates. Strong inter-method agreement was confirmed.
conclusionLiberal fasting achieves equivalent GFV control compared to conventional protocols while optimizing patient comfort, supporting its safe implementation in painless gastroscopy.
