Disproportionality Analysis of Osimertinib-related Adverse Events in Elderly Patients Using the Japanese Pharmacovigilance Database.
Article in Cancer diagnosis & prognosis. 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
Background/Aim: Osimertinib is a well-tolerated first- or second-line treatment option for elderly patients with epidermal growth factor receptor mutation-positive advanced non-small cell lung cancer. However, the safety of osimertinib in elderly patients requires further investigation. Herein, we identified safety signals for various osimertinib-related adverse events (AEs) in elderly patients by disproportionality analysis using the Japanese Adverse Drug Event Report (JADER) database. Patients and Methods: Data from the JADER database from April 2004 to March 2023 were obtained from the Pharmaceuticals and Medical Devices Agency website. Safety signal detection for osimertinib-related AEs in elderly patients (≥70 years old) was determined using the relative elderly reporting odds ratio (ROR). For osimertinib-related AEs, we extracted 92 preferred terms (PTs) and nine standardized MedDRA queries (SMQs). Results: Safety signals in elderly patients were detected for "Cardiomyopathy (PT)" and "Cardiomyopathy (SMQ)". The symptoms most frequently associated with "Cardiomyopathy (SMQ)" included "Ejection fraction decreased (PT)", "Cardiomyopathy (PT)", and "Stress cardiomyopathy (PT)". Notably, 53.7% of these outcomes were "Recovery" or "Remission". The median time to the onset of "Cardiomyopathy (SMQ)" in elderly patients was 85 days (range=2-537 days). Conclusion: We demonstrated that patients ≥70 years potentially have increased osimertinib-related cardiomyopathy compared with patients <70 years. In the future, it is necessary to conduct research focusing on cardiomyopathy in elderly patients.
