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
Background: The use of endobronchial ultrasound-guided core biopsy (EBUS-CB) using forceps or cryoprobes to obtain true histological samples has improved the diagnostic yield for mediastinal and hilar lymphadenopathy. Tract creation in the bronchial wall of the central airway is primarily performed using electrocautery devices in EBUS-CB; however, their poor maneuverability and the risk of vascular injury and damage to the tip of the bronchoscope have prevented the application of EBUS-CB for diagnosing intrapulmonary lesions beyond the central locations. This report presents three cases wherein a 25-gauge transbronchial needle aspiration (TBNA) needle with high flexibility and safety was used to create a tract in the bronchial wall for EBUS-CB of the intrapulmonary lesions adjacent to the bronchi. Case Description: In all cases, EBUS-TBNA using a 25-gauge TBNA needle was performed on the intrapulmonary lesions adjacent to the bronchi, followed by EBUS-CB with 1.9-mm forceps in two cases and also with a 1.1-mm cryoprobe in one case. The EBUS-TBNA specimens revealed no abnormality or only a small number of tumor cells. However, subsequent EBUS-CB, through the tract created by EBUS-TBNA, enabled the collection of a sufficient amount of histological samples with well-preserved histoarchitecture. The histological diagnosis was made via immunostaining, and multigene mutation testing was also successfully analyzed. Conclusions: The use of a 25-gauge needle for creating a tract allows EBUS-CB for the intrapulmonary lesions and may allow for the collection of sufficient histological samples for biomarker analysis and tissue diagnosis.
