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-guided transbronchial needle aspiration (EBUS-TBNA) is widely used for evaluating mediastinal lymphadenopathy. However, its safety profile requires comprehensive evaluation. This study aimed to determine the prevalence of complications associated with EBUS-TBNA and to conduct a systematic review and meta-analysis to estimate the pooled complication rates.
methodsWe retrospectively analysed a prospectively maintained database of patients who underwent EBUS between April 2011 and April 2025. We extracted demographic, procedural, and complication-related data. Major complications were defined as events necessitating endotracheal intubation, cardiopulmonary arrest, hospitalization ≥24 h, mediastinitis, significant bleeding requiring intervention, pneumothorax unrelated to transbronchial biopsy, or death. A systematic review and meta-analysis were performed using the Der Simonian and Laird random-effects model to determine pooled complication rates from studies with ≥1000 EBUS procedures.
resultsOf the 3,454 patients included 77 (2.2%) experienced complications, with 10 (0.3%) classified as major. Major events included severe bleeding ( n = 4), respiratory arrest ( n = 2), mediastinal cyst rupture, mediastinitis, temporomandibular joint dislocation, and one death. The meta-analysis included 27,560 patients from seven studies and yielded a pooled complication rate of 1.21%. The pooled complication rates from our meta-analysis were 26.2 for major bleeding, 9.6 for mediastinitis, 5.5 for pneumothorax, and 1.52 for procedure-related mortality per 10,000 EBUS procedures.
conclusionsEBUS-TBNA is a safe diagnostic procedure with a rare incidence of major complications. Bleeding, infectious complications, and respiratory events constitute the most significant risks.
