Feasibility and Safety of 1.1-mm Cryobiopsy for Acute Rejection Surveillance in Lung Transplant Recipients: A Comparative Study and Review of the Literature.

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
backgroundIdentifying graft rejection after lung transplantation remains challenging, and no consensus exists on the optimal surveillance strategy. Transbronchial forceps biopsy (FBx) is the conventional method but is limited by small sample size and crush artifacts. Sheath-guided cryobiopsy (CBx) using a novel 1.1-mm probe has emerged as a promising alternative. This study evaluates the feasibility and safety of the 1.1-mm cryoprobe and provides a focused review of current literature.
methodsWe conducted a retrospective observational single-center study between October 2022 and January 2023 of adult lung transplant recipients who underwent transbronchial biopsies for surveillance. Procedures were performed using either standard FBx or the 1.1-mm cryoprobe. Descriptive analyses compared feasibility and safety between groups.
resultsWe identified 72 lung transplant recipients who underwent 109 surveillance biopsies. A total of n = 56 CBx and n = 53 FBx procedures were performed. The median procedure time was 20 min (IQR 17-26) in the CBx group versus 22 min (IQR 15-33) in the FBx group. We found a statistically higher median sample area for CBx compared with FBx (11 vs. 6 mm
conclusionCBx with a 1.1-mm probe provides larger histological samples than FBx, with comparable safety and potentially shorter procedural times. These findings support its feasibility for lung transplant surveillance.
