1 · What the graph read from 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.

2 · The registry

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

introductionPoint-of-care gastric ultrasound is an emerging tool in peri-operative practice. However, data on the technical challenges of gastric ultrasound, which are essential for optimised training, remain scarce. We analysed gastric ultrasound examinations performed after basic training to identify factors associated with difficulty.

methodsThis was an analysis of data from a prospective observational study evaluating the potential impact of routine pre-operative gastric ultrasound on peri-operative management in adult patients undergoing elective or emergency surgery at a single centre. Before initiation, physicians received extensive structured training with at least 30 supervised gastric sonograms before independent practice. We then used regression models to identify factors associated with deviation from a predefined sonography algorithm, performance time and scan difficulty.

resultsSeventy-three trained physicians performed 2003 ultrasound scans. Median (IQR [range]) performance time was 5 (4-6 [1-20]) min, which was achieved after 20-27 scans following structured training. Patient characteristics associated with more difficult and longer duration scans were: increase in BMI per 5 kg.m DISCUSSION: Approximately 50 scans are required to achieve a baseline performance of 5 min per gastric ultrasound. Future training programmes should focus on patients with obesity, male sex, higher ASA physical status and trauma.
