Replacement of warfarin with a novel oral anticoagulant in endoscopic mucosal resection: a multicentre, open-label, randomised controlled trial.

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.
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
introductionThis randomised controlled trial aims to compare the efficacy of warfarin replacement with apixaban without postoperative resumption of heparin with that of conventional heparin bridging in patients taking warfarin and scheduled to undergo endoscopic mucosal resection (EMR): specifically, by checking for reduction in proportion of postoperative bleeding following EMR. METHODS AND ANALYSIS: The multicentre, open-label randomised parallel-group, controlled intervention study regards patients taking warfarin who are scheduled to undergo colon EMR. Enrolled patients have been taking oral warfarin for non-valvular atrial fibrillation or venous thrombosis on an outpatient basis, and have been found to have a colorectal polyp (including adenoma or early-stage cancer) for which EMR was indicated. They are assigned to one of two groups. The primary endpoint is proportion of postoperative bleeding. The secondary endpoints are hospital stay length, therapeutic endoscopy outcomes such as proportion of en bloc resection, proportion of perforation, proportion of intraoperative bleeding, incidence of cerebral infarction/systemic embolism events, incidence of adverse events and serious adverse events, and proportion of postoperative therapeutic endoscopy. ETHICS AND DISSEMINATION: This trial was approved by the National Hospital Organization Central Review Board for Clinical Trials (19 April 2016). DISCUSSION: The paucity of reports with high evidence levels was considered problematic when the Japan Gastroenterological Endoscopy Society's gastroenterological endoscopy guidelines were revised in 2012. The results of this trial will have high medical significance, as its data could serve as the basis for revisions in the next edition of the guidelines. TRIAL REGISTRATION NUMBER: This trial was registered in the University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR) accepted from the International Committee of Medical Journal Editors (ICMJE).
