Trial Outcomes & Findings for The Effects Of Ropinirole On Mood Or Mild Depression In Patients With Moderate To Severe Restless Legs Syndrome (NCT NCT00357097)

NCT ID: NCT00357097

Last Updated: 2012-06-07

Results Overview

Montgomery-Asberg Depression Rating Scale (MADRS)is a 10 item questionaire preformed during a clinical interview asking broad to detailed questions about symptoms which allows a precise rating of severity of symptoms of the past week. Questions are scored 0-6. Total Score 0-60, the higher the score indicates the most severely depressed patients.
