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
Introduction: Rigid endoscopes have allowed surgeons to safely perform endoscopic sinus surgery. However, their rigid nature creates inherent visualization limitations. The study herein looks to assess the visualization potential of a novel articulating rigid-flexible endoscope when compared with traditional rigid and flexible nasal endoscopes. Methods: A new articulating endoscope capable of bending its distal tip and extending beyond the point of angulation was compared with 0- and 30-degree 4.0-mm rigid endoscopes, and a 3.7-mm flexible nasopharyngoscope in their ability to visualize predefined anatomic landmarks within the maxillary, sphenoid, and frontal sinuses. Visible markers were placed at applicable landmarks using image guidance in a total of five cadaveric heads. The ability to visualize these intrasinus anatomic landmarks was recorded for each scope. Results: When inspecting the surgically naive anatomy of all sinus ostia and predefined anatomic landmarks, the articulating endoscope had superior visualization ( Conclusion: The articulating rigid-flexible endoscope is superior in reaching and visualizing anatomic landmarks within the paranasal sinuses, compared with standard endoscopes.
