Reporting Groups
  Description
Ropinirole Subjects who were treated on day 1-2 with 0.25 mg/day of ropinirole and on days 3-7 0.5 mg for 12 weeks if tolerated. After two weeks, dose could be increased weekly by 0.5mg a day up to 4 mg maximum dose.
Placebo Subjects who took no investigational product.

Measure Type Secondary
Measure Title Average Change of the MADRS (Montgomery-Asberg Depression Rating Scale) Total Score From Baseline to Final Visit After 12 Weeks of Treatment in Participants With Signs of at Least Moderate Depression (MADRS Score: >=18)
Measure Description 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.
Time Frame Baseline and Week 12  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Modified Intent to Treat (mITT): All treated patients with MADRS score at baseline and post baseline (i.e., at visit 4 and/or 5). Sub-population with MADRS scores>=18: Ropinirole 91 and Placebo 29. The high/Low scores for the mITT population were 32/11.

Reporting Groups
