1 · What the graph read from it

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.

2 · The registry

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

Background: Accurate localization of small-to-medium pulmonary nodules before video-assisted thoracoscopic surgery (VATS) is essential for success. Traditional imaging methods face challenges in the thoracic cavity. This study compares electromagnetic navigational bronchoscopic (ENB), computed tomography (CT)-guided localization effectiveness and safety with methylene blue marker dye. Materials and Methods: This study, approved on May 4, 2024 by the Institutional Review Board of Wuhan Union Hospital (IRB ID UHCT240340) affiliated with Tongji Medical College, included patients with pulmonary nodules scheduled for VATS. Methylene blue was used as a marker dye and injected via CT-guided percutaneous or ENB techniques. The study compared clinical parameters, success rates, and complications between the two localization methods. Results: Out of 378 patients who underwent preoperative localization, 254 received electromagnetic navigational bronchoscopy (ENB) and 124 had CT-guided percutaneous marker dye injections. Nodules were significantly larger in the ENB group ( Conclusions: ENB localization success rates are comparable to CT-guided methods, but ENB carries lower risks, particularly for puncture-related complications. CT-guided localization is more effective than ENB for lower lobe nodules.
