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

backgroundAccurate T-staging of early gastric cancer (EGC) is critical for selecting the most appropriate treatment strategy. Although the reported diagnostic performance of endoscopic ultrasound (EUS) in determining T stage varies among studies, it continues to serve as an important tool in the pretreatment assessment of EGC.

aimTo identify clinicopathological factors that affect the diagnostic accuracy of EUS in EGC, with particular emphasis on mucosal lesions (Tis/T1a).

methodsWe included EGC patients who underwent endoscopic resection or gastrectomy. The diagnostic accuracy of EUS was assessed by comparing its T-stage evaluation with the histopathological results of the resected specimens. Additionally, potential risk factors associated with the over staging of Tis/T1a lesions by EUS were investigated.

resultsA total of 209 patients were included in this study. The overall diagnostic accuracy of EUS for T staging was 74.64%. However, the sensitivity of EUS in identifying Tis/T1a gastric cancers was relatively low at 41.25%. Risk factor analysis showed that younger age (

conclusionThe accuracy of EUS for staging Tis/T1a early gastric cancer is markedly reduced when gastric ulceration is present. Therefore, EUS-based staging should be interpreted cautiously in patients with ulcer-related lesions.
