Article in Gastrointestinal endoscopy, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01688687 (The Accuracy of Probe-based Confocal Endomicroscopy Versus Conventional Biopsies for the Diagnosis of Superficial Gastric Neoplasias), which is not on this map.

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.

Abstract

backgroundConfocal laser endomicroscopy (CLE) allows real-time in vivo histologic evaluation of GI lesions. To our knowledge, there is no reported prospective study comparing endoscopic and optical biopsy using CLE before endoscopic submucosal dissection (ESD) with post-ESD histopathology.

objectiveWe compared endoscopic and optical biopsy before ESD and thereby assessed the ability of CLE to effectively diagnose and differentiate gastric epithelial neoplasia.

designSingle tertiary-care center, prospective comparative study.

settingSoonchunhyang University Hospital, between September 2009 and April 2010. PATIENTS: This study involved 31 patients with 35 gastric epithelial neoplasias, previously diagnosed by endoscopic biopsy, who were scheduled for ESD.

interventionTarget lesions were imaged in vivo by using CLE. MAIN OUTCOME MEASUREMENTS: The overall accuracy of endoscopic and CLE diagnosis was compared with post-ESD histopathology.

resultsIn histopathology after ESD, 11 of 35 lesions (31.5%) were adenomas and 24 (68.5%) were adenocarcinomas. The overall accuracy of CLE diagnosis of gastric adenomas and adenocarcinomas was significantly higher at 94.2% (95% confidence interval [CI], 81.3-98.4), versus 85.7% (95% CI, 70.6-93.7) for endoscopic biopsy (P = .031). The overall accuracy of CLE diagnosis of differentiated and undifferentiated adenocarcinomas also was higher (95.4%; 95% CI, 78.2-99.1) than that of endoscopic biopsy (84.2%; 95% CI, 62.4-94.4) but did not differ significantly (P = .146). LIMITATIONS: Single tertiary-care center experience and small patient number.

conclusionThis study demonstrates the high accuracy of diagnosis of gastric epithelial neoplasia by using CLE. The use of CLE could possibly thus reduce the number of unnecessary biopsies and mistaken diagnoses before ESD.
