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

backgroundGastric emptying scintigraphy (GES) is the reference standard for gastroparesis but is limited by time, cost, and accessibility. We aimed to validate a practical 15-minute gastric ultrasonography (GUS) threshold for early assessment of suspected gastroparesis. MATERIALS AND

methodsWe conducted a prospective diagnostic accuracy study comparing GUS with GES. Participants were divided into training and validation cohorts by enrollment date. Using 4-hour GES as reference, the optimal GUS cut-off was derived by ROC analysis in the training cohort and tested in the validation cohort. Reproducibility and associations with symptom severity were assessed.

resultsOf 123 participants screened, 113 completed both GUS and GES (training, n = 67; validation, n = 46). GUS
