Measure Type	Secondary
Measure Title	Change From Baseline to Week 12/EW in Pittsburgh Sleep Quality Index (PSQI) Total Score by Domains
Measure Description	The PSQI generates seven scores that correspond to different domains. Each component score ranges from 0 (no difficulty) to 3 (severe difficulty). The domain scores are totaled to produce a global score (range of 0–21). A PSQI global score > 5 is considered to be suggestive of significant sleep disturbance.
Time Frame	Baseline - Week 12/EW
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.

Reporting Groups

	Description
Ropinirole CR-RLS	Subjects who took oral Ropinirole CR-RLS once daily 1-2 hours before onset of Restless Legs Syndrome (RLS) symptoms (after 4pm). Initial dose level was 0.5 mg/day and increased weekly by 1 mg/day until sufficient efficacy was obtained without any tolerability issues. Treatment period was 12 weeks. Maximum dose level was 6 mg per day.

Certain Agreements:

Principal Investigators are NOT employed by the organization sponsoring the study.

There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.

The agreement is:

	The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
	The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
	Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed. Restriction Description: GSK agreements may vary with individual investigators but will not prohibit any investigator from publishing. GSK supports the publication of results from all centers of the multi-center trial but requests that reports based on single-site data not preceed the primary publication of the entire clinical trial.

Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
