Successful Mediastinal Cryobiopsy Using the Slim UCP190F EBUS Bronchoscope and a 25G Needle: Demonstrating the Efficacy of the Ariza-Pallares Approach.
Article in Respirology case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Mediastinal cryobiopsy is emerging as a powerful adjunct to traditional EBUS-TBNA, offering larger, architecturally preserved tissue samples. We describe a case demonstrating successful mediastinal cryobiopsy using the newly developed UCP190F endobronchial ultrasound (EBUS) bronchoscope in a patient with a right upper lobe lesion and mediastinal lymphadenopathy. Owing to the device's narrow 1.7 mm working channel, only 25-gauge needles (0.4 mm diameter) can be used, raising concerns regarding the feasibility of creating a sufficiently stable access tract for introducing a 1.1 mm cryoprobe for mediastinal cryobiopsy. Using the Ariza-Pallares four-step method, a navigable tunnel into station 7 was successfully created, enabling safe cryobiopsy and yielding high-quality histologic samples. This case demonstrates that mediastinal cryobiopsy can be successfully performed even with very small-gauge needles and with new-generation thin convex-probe scopes, expanding the applicability of cryobiopsy across EBUS platforms.
