Primary lung adenocarcinoma mimicking recurrent pneumonia in a young adult.
Article in BMJ case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
A man in his 20s with a history of tobacco use presented with recurrent shortness of breath. He was hospitalised three times within the past 4 months for similar symptoms despite completing several courses of antibiotic therapy. In this presentation, he was afebrile with rhonchi and decreased breath sounds over the right lung. Chest CT demonstrated large consolidations in the right middle and lower lobes, worsened compared with 4 months prior. Infectious workup including bronchoscopy with bronchoalveolar lavage did not identify a causative organism. Testing for immune disease was negative. Transbronchial biopsy ultimately identified well-differentiated stage 3b lung adenocarcinoma with a KRAS G12C mutation. The patient was referred to oncology for outpatient follow-up and has since initiated chemotherapy. This case highlights diagnostic biases encountered in young patients and the utility of bronchoscopic biopsy for definitive diagnosis in presumed community-acquired pneumonia when the clinical outcome is not improving as expected.
