Rapid On-Site Digital Histopatholocal Evaluation (RODE) on Endobronchial Ultrasound (EBUS) Mediastinal Lymph Node Cryobiopsy Sampling Using Confocal Laser Microscopy-A Proof-Of-Concept Study.
Article in Respirology case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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
The current standard for determining sample adequacy during Endobronchial Ultrasound guided Mediastinal Sampling is ROSE (Rapid on-site Evaluation) on samples obtained by Fine needle Aspiration. There is an increasing interest in Mediastinal Lymph node cryobiopsy, where tissue samples are obtained using a 1.1 mm cryoprobe. Rapid onsite evaluation on cryobiopsy samples can also be performed by imprint cytology. This proof-of-concept study explores the use of Viva Scope 2500 for rapid on-site digital histopathological evaluation of Endobronchial Ultrasound (EBUS) guided mediastinal lymph node cryobiopsy samples. Confocal Laser Microscopy allows for high-resolution imaging and expedites diagnosis. The study involved four cases of mediastinal lymph node cryobiopsy, and the samples obtained were subjected to rapid digital histopathological examination by Viva Scope 2500 (confocal laser microscopy), enabling lesion in tool confirmation and the results obtained were compared with the final conventional histopathology results. Confocal Laser microscopy by Viva Scope 2500 was found to be comparable to conventional histopathology, superior to conventional histopathology in providing rapid on-site diagnosis minimising the time to diagnosis, with added advantage of better sampled tissue preservation for downstream molecular analysis. RODE reduces procedural time and increases confidence in the operator during mediastinal lymph node sampling enabling lesion in tool confirmation. RODE is a better alternative to ROSE and conventional histopathology decreasing the time to diagnosis.
