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
purposeTo carry out a pilot study to evaluate the efficacy of a novel, drivable endoscope (the Peregrine™ Drivable ENT Scope), compared to standard rigid endoscopes in the access, visualization, and irrigation of the paranasal sinus anatomy.
methodsA prospective, multi-center, feasibility study was conducted on seventeen subjects who underwent primary functional endoscopic sinus surgery and were evaluated with the drivable endoscope and standard, rigid endoscopes (0°, 30° and 70°, as applicable). A CT scan was available for image guidance, as needed. The primary efficacy endpoint was the ability to access and visualize sinonasal anatomic landmarks. Secondary endpoints included device usability, as measured by a usability questionnaire given to surgeons postoperatively; the device's ability to irrigate the sinuses and patient reports of tolerability and pain during postoperative procedures.
resultsThe drivable endoscope success rate in visualizing all paranasal sinus anatomic landmarks was 55.6% better than the standard rigid endoscopes: 98.3% (178/181) versus 42.7% (76/178); p < 0.001. Surgeons rated scores of over 4 (on a 1-5 scale) for the usability of the drivable endoscope to enter the maxillary, frontal and sphenoid sinuses. The ability to irrigate the sinuses using the drivable endoscope was given a mean score of 4.3, and image quality was given a mean score of 3.4. The three patients evaluated postoperatively reported low pain and high tolerability scores with the drivable endoscope.
conclusionsThese preliminary results indicate that the drivable endoscope is effective, easy to use and highly tolerable in sinonasal endoscopy.
