The Bird's Nest Sign as an Initial Presentation of Primary Pulmonary B-Cell Non-Hodgkin Lymphoma With Plasmacytic Differentiation.

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
The bird's nest sign (BNS) has been described as a sign on chest computed tomography (CT) in various pulmonary diseases. We report a rare case of primary pulmonary B-cell non-Hodgkin lymphoma with plasmacytic differentiation presenting with BNS, mimicking an invasive fungal disease at first. A 61-year-old Vietnamese man with a history of idiopathic thrombocytopenia and splenectomy 3 years prior to admission presented with prolonged dry cough, mild dyspnoea on exertion and chest discomfort for 3 weeks. His laboratory tests were unremarkable, but his chest CT showed bilateral consolidation with the BNS. After an unfavourable response to anti-fungal therapy, the second transthoracic lung biopsy confirmed the diagnosis of primary pulmonary B-cell non-Hodgkin lymphoma with plasmacytic differentiation. This case highlights the importance of considering lymphoma in the differential diagnosis of BNS when infection is excluded and concurrently seeking a confirmatory diagnosis with repeated diagnostic procedures when necessary.
