Scan features scored 0.83 versus 0.74 for a clinical risk score in distinguishing who developed the condition; 1 would mean perfect separation.Scan features scored 0.83 versus 0.74 for a clinical risk score in distinguishing who developed the condition; 1 would mean perfect separation.
For 10-year heart failure prediction, a scan-based model scored 0.84 versus 0.72 for a clinical score in distinguishing future cases from people who remained unaffected.For 10-year heart failure prediction, a scan-based model scored 0.84 versus 0.72 for a clinical score in distinguishing future cases from people who remained unaffected.
