Performance of radial endobronchial ultrasound for peripheral pulmonary lesions without automation technology in tuberculous endemic region: real-world experience in a single institution over 6 years.

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: Peripheral pulmonary lesions (PPLs) in tuberculous endemic regions present a unique diagnostic challenge, as tuberculous PPL can mimic malignancy and potentially delay diagnosis for both conditions without a confirmatory investigation. While bronchoscopic biopsy using radial endobronchial ultrasound (rEBUS) guidance is becoming more common among pulmonologists, it is often performed with additional automation technology such as virtual bronchoscopic and electromagnetic navigation. This study aimed to evaluate the performance of rEBUS without such automation technology over a 6-year period in our institution. Methods: Retrospective chart review of all adult patients undergoing rEBUS-guided transbronchial biopsy for PPL in our institution over 6 years duration (October 2016 to December 2022). Results: A total of 551 PPLs were included with median target lesion size of 2.70 (interquartile range, 2.10-3.70) cm. In total, 84.2% of lesion demonstrated direct bronchus sign with 46.3% demonstrating concentric rEBUS orientation. The overall diagnostic yield was 78.8% [95% confidence interval (CI): 75.1-82.1%], with 1.1% rate of pneumothorax. Among the conclusive cases, 62.7% were malignant while 37.3% were tuberculous. Bronchus sign [adjusted odds ratio (adj. OR): 2.268] and concentric rEBUS orientation (adj. OR: 3.426) are independent predictors for conclusive procedure. The sensitivity of rEBUS for malignant and tuberculous disease was 85.27% (95% CI: 80.89-88.97%) and 71.77% (95% CI: 62.99-79.49%) respectively. A significant improving trend of diagnostic yield over time with reduction of median PPL size was observed with introduction of cryobiopsy and thin bronchoscopy into rEBUS service. Conclusions: rEBUS without automation technology remains relevant and useful in this era. rEBUS provides a rapid and safe diagnosis of PPL which may translate into better patient care.
