Shape-sensing robotic-assisted versus electromagnetic navigation bronchoscopy for peripheral pulmonary lesions: a single-operator experience.

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 shape sensing robotic assisted bronchoscopy (ssRAB) are used to sample peripheral pulmonary lesions (PPLs). Comparative data between ENB and ssRAB, particularly in the absence of advanced three-dimensional imaging, remain limited. We compared the performance of ENB and ssRAB performed by a single interventional pulmonologist at a large urban hospital. Methods: We performed a single-center retrospective analysis of ENB procedures performed between December 2020 and June 2023 and ssRAB procedures performed between September 2023 and August 2024. All procedures used radial endobronchial ultrasound and two-dimensional fluoroscopy. Neither modality was used with cone beam computed tomography (CT), digital tomosynthesis, or rapid on-site evaluation. Diagnostic yield, final diagnostic accuracy, number of procedures required to establish a diagnosis of malignancy, and complications were compared. Results: A total of 359 patients were included (ENB 226; ssRAB 133). Strict diagnostic yield from the index procedure was 64% for both technologies. Final diagnostic accuracy was 71.2% for ENB and 76% for ssRAB (P=0.39). Patients undergoing ssRAB required fewer procedures to establish a malignant diagnosis, with 84.6% diagnosed after a single procedure compared with 60.8% for ENB (P=0.007). PPLs sampled with ssRAB were smaller than those sampled with ENB (median size 1.7 Conclusions: In this single operator, large hospital experience, ssRAB achieved similar diagnostic yield to ENB while sampling smaller PPLs and requiring fewer procedures to obtain a final malignant diagnosis. These findings suggest the feasibility of integrating ssRAB into large hospital settings even if staffed by one interventional pulmonologist.
