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

Increasing familiarity with advanced endoscopic excision techniques allows for more colorectal lesions to be removed without major surgery. Endoscopic excision with negative margins is adequate for most polyps and low-risk T1 cancers. The use of modern polyp classification techniques based on size, morphology and pit pattern by an experienced endoscopist allow for an optical diagnosis of these lesions and can predict, with high accuracy, which lesions contain malignant disease and the level of invasion. A surgeon endoscopist must be able to recognize which complex polyps can be resected with advanced polypectomy techniques and which require upfront surgery. We aimed to provide an overview of polyp classification techniques to help surgeons select the correct treatment algorithm for advanced colorectal lesions based on their visual characteristics at index endoscopy.
