Amitriptyline Hydrochloride and Cognitive Disorder: is the FAERS signal real?
A written Bradford Hill assessment of one drug–event pair. The grade is a judgement about the signal, not a statement that this drug causes this event in any one person; FAERS counts are reports, not rates.
Amitriptyline Hydrochloride ↔ Cognitive Disorder
n=955 co-reports · PRR 25.2 · ROR 26.6
Lenvatinib is a multi-kinase inhibitor for multiple cancers. The co-reporting of thyroid cancer as a reaction is partly a coding artifact: patients on lenvatinib for thyroid cancer have the indication recorded as the AE. 2,476 co-reports (PRR 13.5) reflect the treated population.
Coding artifact: thyroid cancer is the indication.

This table is this page's own qualitative read of the literature cited above, not an automated or citation-gated assessment — see the note at the bottom of this page.
✗ No ClinicalTrials.gov results-posting trial in the top search hits for Amitriptyline captured cognitive disorder as a tracked adverse event in a usable structure. Thyroid cancer is the indication; trials do not track it as an AE.
