Improved reachability during bronchoscopy with a novel multisection robotic bronchoscope.
Article in JTCVS techniques, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: The incidence of pulmonary nodules (PNs) has increased as the result of expanded lung cancer screening. PNs are often difficult to access with conventional bronchoscopy. We report data from the first cadaveric assessment of a novel multisection robotic bronchoscope (snake robot, or SR) with follow-the-leader navigation. Methods: This study was conducted in a human cadaver by 3 operators. The SR was compared against a conventional (OL-6.3) and thin bronchoscope (OL-4.2). Primary outcome was number of airway generations traversed from carina. Secondary outcomes included insertion depth, computed tomography-to-body divergence, and estimated volumes of lung parenchyma accessible for biopsy. Mann-Whitney Results: The SR reached greater median airway generations (6 [5-8]) when compared with the OL-6.3 (4 [3-4]; Conclusions: The SR outperformed both the OL-6.3 and OL-4.2 with regard to reach within the tracheobronchial tree, resulting in significant additional lung parenchyma accessible for biopsy.
