Study design for a multicenter, randomized controlled trial evaluating the diagnostic value of ultrathin bronchoscope compared to thin bronchoscope without fluoroscopy for peripheral pulmonary lesions.
Article in Journal of thoracic disease, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04571476 (Diagnostic Value of Ultrathin and Thin Bronchoscope for Peripheral Pulmonary Lesions), which is not on this map. Cited by 2 papers.
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.

Abstract
Background: Ultrathin bronchoscope (UTB) with a 3.0-mm outer diameter and a 1.7-mm working channel currently appeared as a potential tool for better biopsy and diagnosis of peripheral pulmonary lesions (PPLs) by accessing more distal bronchus. However, published research is primarily limited to diagnosis value of UTB for PPLs with fluoroscopy, the value of UTB compared with thin bronchoscope (TB) without fluoroscopy guidance has not been determined yet. Methods: We design a prospective, randomized, controlled, non-inferior, multicenter study aiming to evaluate the diagnostic value and safety of UTB for PPLs with the guidance of virtual bronchoscopic navigation (VBN) combined with endobronchial ultrasound (EBUS) without fluoroscopy by comparing to TB. The study aims to enroll 578 patients presenting for evaluation of PPLs at five clinical sites in China. Subjects will be randomized to UTB-VBN-EBUS group, TB-VBN-EBUS-guide sheath (GS) group, and TB-VBN-EBUS-non-GS group. Primary endpoint is the diagnostic yield of PPLs. The total examination time, duration of finding lesions, the proportion of lesions visible by radial EBUS, factors affecting the diagnostic yield, difference in the bronchus level reached with the bronchoscope, difference in diagnostic yield, and complication rate will be determined as secondary endpoints. The primary endpoint will be followed-up at least 6-month post-procedure and 1-month post-procedure for safety endpoint. Discussion: Study enrollment began in March 2021. Our preliminary experience reveals that UTB is a powerful tool in the diagnosis of PPLs even without fluoroscopy. The results of the current study will compensate the limitations of the previous research, further provide evidence of UTB in diagnosing PPLs without fluoroscopy.
