1 · What the graph read from it

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.

2 · The registry

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

backgroundThe safety data of lecanemab in the post-marketing period has yet to be fully investigated in the current literature. We aimed to identify and characterise the safety profile of lecanemab in the post-marketing period.

methodsWe searched and reviewed the reports submitted to the FDA's Adverse Event Reporting System (FAERS). We used a case/non-case approach to estimate the reporting odds ratio (ROR) and information component (IC) with 95% confidence intervals (CI) for lecanemab-related adverse events (AEs) reported at least four counts. We compared the difference between serious and non-serious reports using non-parametric tests.

resultsThe FAERS recorded 1,986 lecanemab-related AEs affecting 868 patients. Two hundred and three patients experienced serious AEs, including 22 deaths. The most frequently reported AEs were headache (n = 193), chills (n = 100), fatigue (n = 93), and amyloid-related imaging abnormality-oedema/effusion (ARIA-E) (n = 91). Safety signals were detected, such as headache (ROR: 10.4, 95%CI: 8.97, 12.07; IC: 3.25, 95%CI: 2.97, 3.40), ARIA-E (ROR: 18,299.69, 95%CI: 14,001.27, 23,917.73; IC: 13.37, 95%CI: 6.15, 6.87), and infusion-related reaction (ROR: 35.25, 95CI 27.58, 45.07; IC: 5.09, 95CI 4.15, 4.87). We also identified several new AEs, such as migraine and pancreatic carcinoma. Patients with serious AEs were more likely to be on polypharmacy for Alzheimer's disease and use aspirin, acid-suppressing medications, statins, antidepressants, or benzodiazepines compared to those with non-serious AEs.

conclusionsLecanemab may have a significant potential for AEs. Our results provide evidence for healthcare professionals and patients to weigh the risks and benefits of lecanemab treatment. Further prospective studies are needed to explore rare and unexpected AEs.
