Safety and factors affecting diagnostic yield in modified virtual bronchoscopy-guided transparenchymal nodule access for pulmonary lesions.

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
backgroundWith the advent of low-dose computed tomography (CT) screening, minimally invasive evaluation of pulmonary lesions has become increasingly important. This study aimed to assess factors influencing the diagnostic yield of novel bronchoscopic transparenchymal nodule access (BTPNA) method for diagnosing pulmonary lesions in a real-world clinical setting.
methodsThis retrospective study evaluated patients who underwent BTPNA with or without real-time image guidance for pulmonary lesion assessment. Lesions were deemed inaccessible if a diagnosis could not be obtained via CT-guided transthoracic biopsy or conventional bronchoscopy. CT images for each patient were used to reconstruct a navigation map and design a point of entry (POE) along the airway wall through the lung parenchyma to the lesion. Patients were monitored for more than 48 h after BTPNA.
resultsBetween January 2022 and July 2024, 17 patients underwent BTPNA without adverse events requiring immediate treatment during the procedures. Adequate biopsies were obtained from 15 patients for whom a tunnel path was created. The overall diagnostic yield was 77%, influenced by nodule size, CT morphology, and the chosen path. Real-time guidance during BTPNA and airway diameter at the POE did not significantly affect the diagnostic yield in this analysis.
conclusionBTPNA has shown potential as a high-yield and safe diagnostic technique for patients in whom alternative methods were considered unsuitable due to safety concerns or low expected diagnostic yield.
