Co-Occurrence of Rheumatoid Arthritis and Lung Cancer-Coincidence or Not?
Article in Life (Basel, Switzerland), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Bronchopulmonary cancer is the leading cause of cancer deaths globally. Rheumatoid arthritis is one of the risk factors for lung cancer, and those who use methotrexate have a higher risk of developing lung cancer. We present the case of an 80-year-old patient who is a former smoker and is known to have rheumatoid arthritis, being treated using methotrexate; they were brought by ambulance to the emergency room for coughing with ineffective expectoration, dyspnea on slight exertion, and right-lateral chest pain with onset about one month prior and progressive worsening. Imaging showed a 7 cm/6 cm LID tumorous lung formation with parietal invasion and C7 rib lysis, as well as diffuse fibrotic interstitial changes predominantly in the lower lobes. An ultrasound-guided transthoracic lung biopsy was performed, and histopathological examination established the diagnosis of invasive squamous cell lung carcinoma, G2. In conclusion, the chest pain interpreted by the patient as rheumatic pain delayed the diagnosis of lung cancer; the patient presented rather late to the hospital once respiratory failure set in.
