Comparison of learning curves between electromagnetic navigation bronchoscopy and Ion robotic bronchoscopy for preoperative localization.

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: Electromagnetic navigation bronchoscopy (ENB) and Ion robotic bronchoscopy are novel, high-precision techniques with low complication rates for the preoperative localization of peripheral pulmonary nodules (PPNs). Their clinical application is largely influenced by the operator's learning curve; however, direct, systematic comparisons of the learning curves between these two techniques are scarce. This study therefore aimed to analyze differences in the learning curves between ENB and Ion robotic bronchoscopy for PPN localization. Methods: A retrospective analysis was performed on the perioperative data of 120 patients who underwent preoperative PPN localization (60 consecutive ENB-guided cases and 60 Ion robotic bronchoscopy-guided cases) from September 2024 to June 2025. All procedures were performed by the same thoracic surgeon. The clinical characteristics of the two groups were compared, and the cumulative sum (CUSUM) method was employed to analyze operative time (OT). Results: Perioperative comparisons revealed that the ENB group had a significantly shorter OT (17.13 Conclusions: This study demonstrates that ENB-guided PPN localization has a shorter learning curve than Ion robotic bronchoscopy, while the latter achieves a higher localization success rate.
