Predicting Diagnostic Success and Procedural Efficiency in Robotic Bronchoscopy Using Machine Learning.
Article in Diseases (Basel, Switzerland), 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
backgroundRobotic-assisted bronchoscopy with the ION™ Endoluminal System facilitates precise access to peripheral pulmonary lesions. However, procedural duration and diagnostic performance remain influenced by patient and lesion-specific factors. To investigate the impact of lesion diameter, radiological appearance, and presence of bronchial signs on procedural duration and diagnostic yield using conventional regression and gradient boosting machine learning models.
methodsIn this single-center retrospective cohort study, 189 ION™ Endoluminal System procedures (November 2024-June 2025) were analyzed. Procedural duration and diagnostic yield served as primary outcomes. Predictive modeling included multivariable regression and gradient boosting. Feature importance metrics were extracted.
resultsThe median lesion diameter was 12.3 mm, with a "strict" diagnostic yield of 87.3%. Gradient boosting regression identified lesion diameter as the primary predictor of procedural time (89.2% importance; test MSE = 865.6). Diagnostic classification achieved an ROC-AUC of 0.68, with lesion diameter (85.8%) and bronchial sign (14.2%) as key predictors.
conclusionsLesion diameter emerged as the most consistent predictor of procedural efficiency and was associated with diagnostic performance, albeit within the limitations of the dataset. Broader datasets are needed for external validation and generalizability.
