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: Accurate diagnosis of newly emerging peripheral pulmonary lesions (PPLs) after pulmonary resection for malignancies is essential for a favorable prognosis. We aimed to investigate the diagnostic utility and safety of bronchoscopy for PPLs after pulmonary resection of malignant tumors and to evaluate the effect of prior surgery on the diagnostic performance. Methods: As a single-center retrospective study, consecutive patients who underwent radial endobronchial ultrasound (R-EBUS)-guided transbronchial biopsy under X-ray fluoroscopic support for PPLs that developed after pulmonary resection of malignancies at National Cancer Center Hospital, Tokyo, Japan between January 2017 and December 2022 were analyzed. Because surgery was considered to influence the architecture of the ipsilateral peripheral bronchi, the diagnostic results were compared between the groups of patients after ipsilateral and contralateral pulmonary resections. Results: In total, 220 patients, 110 each in the ipsilateral and contralateral biopsy groups were analyzed. The overall number of diagnostic cases was 158 of 220 (71.8%), and the diagnostic yield was significantly lower in the ipsilateral biopsy group than in the contralateral biopsy group (62.7% Conclusions: Bronchoscopy had a sufficient diagnostic yield and safety for PPLs after pulmonary resection of malignancies. However, the diagnostic performance was reduced in biopsies ipsilateral to prior resections.
