Anaphylactic Shock Following Multiple Self-Medication Exposures in a Patient With Rheumatoid Arthritis Receiving Methotrexate: A Case Report.
Article in Cureus, 2026. 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
We report a 51-year-old female with rheumatoid arthritis (RA) on long-term methotrexate, hydroxychloroquine, and sulfasalazine, who self-administered multiple medications, including diclofenac 50 mg, without medical supervision. She presented with acute-onset shortness of breath, generalized pruritus, angioedema, and palpitations, and was found to be in severe anaphylaxis with cardiovascular collapse, with a blood pressure of 60/nil mmHg and a heart rate of 143 beats per minute. Diclofenac was considered the most likely trigger based on temporal association and known nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity risk; however, causality cannot be definitively proven as several medications were taken within the same exposure window. Investigations revealed leukocytosis, microcytic anemia, reactive thrombocytosis, and elevated alkaline phosphatase. The electrocardiogram showed no ischemic ST-segment changes or conduction abnormalities. Prompt resuscitation with intramuscular epinephrine resulted in hemodynamic stabilization within 15 minutes of the first dose, with complete angioedema resolution within 30 minutes. The patient was managed without intensive care unit admission and discharged in stable condition on day three. This case highlights the diagnostic and management challenges of severe hypersensitivity reactions occurring in the setting of polypharmacy and emphasizes the importance of individualized analgesic planning and careful medication counseling in patients with RA receiving chronic therapy.
