An Operable, Portable, and Disposable Ultrathin Endoscope for Evaluation of the Upper Gastrointestinal Tract.

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
BACKGROUND AND
aimsA prototype of a disposable endoscope (DE) with easy viewing of the esophagus has been developed. The aim of this study was to develop a new version of DE with improved functionality and to assess the feasibility of DE as a screening tool for upper gastrointestinal diseases compared with conventional endoscopes.
methodsDiagnostic accuracy and maneuverability of DE were evaluated by comparing endoscopy using DE with conventional endoscopy. Different examiners performed DE endoscopy and conventional endoscopy in a randomized order, blinded to the results. Examiners were asked to respond to a questionnaire about ease of handling and observation using DE in preformed result sheets. Tolerability of DE was also evaluated. Non-sedated participants were asked to respond to a questionnaire about the convenience and satisfaction with DE endoscopy on a nine-point Likert scale.
resultsThe overall ease of insertion and handling of DE was excellent. The new device enabled observation and evaluation of the entire esophagus with a good agreement between DE endoscopy and conventional endoscopy in terms of endoscopic diagnosis (Kappa value; hiatal hernia; 0.910, reflux esophagitis; 0.949, Barrett's esophagus, 1.000). Participants suggested that they were more comfortable with DE endoscopy than with conventional endoscopy with a lower symptom score (p = 0.030).
conclusionThe new DE enabled easy observation of the entire esophagus owing to its improved maneuverability, and its diagnostic ability of esophageal diseases was comparable to that of conventional endoscopes. Non-sedated esophagoscopy with this disposable device potentially has widespread applications in outpatient clinics and areas without endoscopic facilities.
