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
Introduction: Endobronchial teratomas are extremely rare tumors that develop within the airway of the lung. Patients often present with nonspecific symptoms that depend on the size and anatomic features, making the differential broad and the diagnosis challenging. Presentation of case: A 28-year-old man presented with a 6-month history of a dry cough, vague chest discomfort, and occasional dyspnea. A chest X-ray and CT were performed, revealing a heterogeneous mass involving the mediastinum and the medial aspect of the right lung. Serum tumor markers were normal, and a testicular ultrasound excluded a metastatic germ cell tumor. Definitive treatment required an Discussion: This case illustrates the diagnostic challenges of endobronchial teratomas, provides imaging and histologic characteristics of this rare tumor type, and contributes to the number of published cases with favorable outcomes. Conclusion: Given the rarity of endobronchial teratomas, a high index of suspicion among pulmonologists, surgeons, and pathologists is necessary to correctly diagnose and treat these patients.
