Pulmonary Rheumatoid Nodules: A Case Report.

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
Rheumatoid arthritis (RA) is an autoimmune disorder primarily targeting joints, with the lungs often being the most affected organ outside the joints. Pulmonary rheumatoid nodules (PRNs) are unusual manifestations of RA in the lungs. We report a case of a 74-year-old Chinese man with a smoking history, diagnosed with RA and treated with leflunomide and prednisone, who showed multiple peripheral or pleural nodules in both lungs on computed tomography (CT) scans. Pathological analysis of the right middle lobe lesion from CT-guided percutaneous core needle biopsy showed lymphocytic and neutrophilic infiltration, eosinophilic necrosis, scattered multinucleated giant cells and no basophilic necrosis or vasculitis. The diagnosis of PRNs was made after thorough examinations and multidisciplinary consultation and tocilizumab was recommended for subsequent therapy. PRNs, a rare extra-articular manifestation of RA, should be distinguished from infections and malignancies. High-resolution chest CT and biopsy can help in the diagnosis.
