"Pseudo-Spleen Sign" on Gastric Ultrasound in the Supine Position: A Case Report of a Patient With Delayed Gastric Emptying.

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
Gastric ultrasound (GUS) plays a key role in identifying delayed gastric emptying and preventing pulmonary aspiration. Conventional GUS estimates gastric volume by measuring the cross-sectional area (CSA) of the antrum in the right lateral decubitus (RLD) position, which is often impractical in respiratory-unstable patients. We report an adult patient in whom GUS in the supine position successfully identified a distended gastric fundus filled with enteral nutrition (EN). In this patient, GUS in the RLD position was not feasible due to a respiratory condition. However, a daily supine abdominal ultrasound using the left upper quadrant (LUQ) view revealed a distended gastric fundus with EN. This finding suggested delayed gastric emptying; thus, we reduced the continuous EN infusion rate. This adjustment, in combination with prokinetic agents and continued clinical monitoring, may have contributed to preventing reflux and aspiration. The ultrasound appearance of the fundus resembled a spleen, and we termed it "pseudo-spleen sign." This supine GUS approach with this novel finding may offer a practical adjunct to conventional GUS that requires the RLD position.
