Evaluation of electromagnetic navigational bronchoscopic biopsy of lung lesions performed by a thoracic surgical service.

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 increasing use of computed tomography scans for lung cancer screening and surveillance of other cancers, thoracic surgeons are being referred patients with lung lesions for biopsies. Electromagnetic navigational bronchoscopy-guided lung biopsy is a relatively new technique for bronchoscopic biopsy. Our objective was to evaluate the diagnostic yields and safety of electromagnetic navigational bronchoscopy-guided lung biopsy.
methodsWe conducted a retrospective review of patients who underwent an electromagnetic navigational bronchoscopy biopsy, performed by a thoracic surgical service, and evaluated its safety and diagnostic accuracy.
resultsIn total, 110 patients (men 46, women 64) underwent electromagnetic navigational bronchoscopy sampling of pulmonary lesions (n = 121; median size 27 mm; interquartile range 17-37 mm). There was no procedure-related mortality. Pneumothorax requiring pigtail drainage occurred in 4 patients (3.5%). Ninety-three (76.9%) of the lesions were malignant. Eighty-seven (71.9%) of the 121 lesions had an accurate diagnosis. Accuracy increased with increased lesion size (P = .0578) with a yield of 50% for lesions <2 cm, increasing to 81% for lesions ≥2 cm. The lesions that demonstrated a positive "bronchus sign" had a yield of 87% (45/52) compared with 61% (42/69) in lesions with a negative "bronchus sign" (P = .0359).
conclusionThoracic surgeons can perform electromagnetic navigational bronchoscopy safely, with minimal morbidity and with good diagnostic yields. Accuracy increases with the presence of a bronchus sign and increasing lesion size. Patients with larger tumors and the bronchus sign may be candidates for this approach to biopsy. Further work is required to define the role of electromagnetic navigational bronchoscopy in the diagnosis of pulmonary lesions.
