A retrospective study comparing the ultrathin versus conventional bronchoscope for performing radial endobronchial ultrasound in the evaluation of peripheral 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
backgroundFew studies have reported on the utility of ultrathin bronchoscopes (UTBs) for performing radial probe endobronchial ultrasound (EBUS). Herein, we describe our experience with UTB and conventional bronchoscope (CB) for performing radial EBUS. MATERIALS AND
methodsThis was a retrospective study comparing the diagnostic yield of a prototype UTB (external diameter 3 mm, working channel diameter 1.7 mm) versus CBs (external diameter ≥4.9 mm) in performing radial EBUS for the evaluation of peripheral pulmonary lesions (PPLs). Fluoroscopic guidance was not available.
resultsA total of 121 subjects (34, UTB; 87, CB; 69.4% males) with a mean (standard deviation [SD]) age of 55.2 (14.8) years underwent radial EBUS. The mean (SD) size of PPLs on computed tomography of the thorax was 22.2 (13.7) mm. The lesions were significantly smaller in the UTB group (16.4 vs 24.7 mm, P = 0.006). Eight lesions could be visualized within the lumen of the peripheral smaller bronchi with the UTB. The overall yield of radial EBUS was 52.9% and was similar in the two groups (UTB vs. CB, 55.9% vs. 51.7%; P = 0.7). The procedure time was significantly shorter in the UTB group. On multivariate logistic regression, the yield was similar in the two groups after adjusting for the size and location of the lesion and position of the radial probe in relation to the lesion.
conclusionDespite smaller lesions, radial EBUS performed with the UTB was found to have similar efficacy to that performed with the CB. More lesions could be visualized endobronchially using the UTB making it an attractive alternative for performing radial EBUS.
