The clinical utility of endobronchial ultrasound-guided transbronchial needle aspiration: A single-center experience from the Middle East.

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
backgroundEndobronchial Ultrasound with Transbronchial Needle Aspiration (EBUS-TBNA) is a well-established tool in evaluating the diverse etiologies of mediastinal lymphadenopathy. The objectives of our study included the estimation of overall, diagnostic yield in different primary tumors, and identification of the factors influencing yield.
methodsThis is a 3-year retrospective analytical study on patients with mediastinal lymph nodes who underwent EBUS-TBNA from January 2022 to December 2024 at Sultan Qaboos Comprehensive Cancer Care and Research Center, Muscat, Oman. The study included only patients with complete pathological and medical records.
resultsOut of the 113 EBUS-TBNA done during the study period, 111 patients were included. The mean age was 60.32 ± 14.69 years. One hundred and sixty-nine nodes were sampled with 861 sampling passes for diagnostic, staging, and molecular in 71.2%, 25.2%, and 3.6%, respectively. A single station was sampled in 67.6%, with station 7 the most common (64.9%). The overall diagnostic yield was 85.6%. Yield varied significantly by primary site (
conclusionsEBUS-TBNA has a high diagnostic yield in mediastinal lymphadenopathy. It should be considered as the primary invasive tool for both diagnostic and staging assessment of mediastinal nodes. However, its limitations are noticeable in suspected lymphoma and molecular analysis, noting that this conclusion is limited by the small sample size.
