How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This case report describes a 64-year-old male who developed subclinical hypothyroidism after three months of low-dose amiodarone (100 mg/day). Routine monitoring showed a TSH increase to 44.40 mU/L with normal FT4 and FT3 levels. Based on the Naranjo scale (score: 7), amiodarone was deemed a probable cause of SCH. This case highlights the importance of routine thyroid monitoring during amiodarone therapy, even at low doses.
