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.

There is evidence that CCM improves quality of life and exercise tolerance of patients. There is no sufficient data that MCC can improve a patients prognosis. We need more data to understand the place of MCC in treatment of patients with CHF.
