Reporting Groups
  Description
Early Pramipexole Patients initially randomized to pramipexole were up-titrated from 0.375 mg pramipexole daily to 0.75 mg pramipexole daily and then to 1.5 mg pramipexole daily over a 6 week period, and then 1.5 mg pramipexole daily was continued for the remainder of the 15 months of the study.
Delayed Pramipexole Patients initially randomized to placebo, received placebo for 6-9 months, then up-titrated from 0.375 mg pramipexole daily to 1.5 mg pramipexole daily over a 6 week period. These patients were then continued on 1.5 mg pramipexole daily for the remainder of the 15 months of the study.

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.
Glucose-N was 28 for Early PPX and 46 for Delayed PPX, Cholesterol and Triglyceride-N was 213 for Early PPX and 208 for Delayed PPX, Blood Urea Nitrogen-N was 214 for Early PPX and 209 for Delayed PPX, Creatinine-N was 200 for Early PPX and 202 for Delayed PPX, Uric Acid-N was 212 for Early PPX and 209 for Delayed PPX.

Reporting Groups
  Description
Early Pramipexole Patients initially randomized to pramipexole were up-titrated from 0.375 mg pramipexole daily to 0.75 mg pramipexole daily and then to 1.5 mg pramipexole daily over a 6 week period, and then 1.5 mg pramipexole daily was continued for the remainder of the 15 months of the study.
Delayed Pramipexole Patients initially randomized to placebo, received placebo for 6-9 months, then up-titrated from 0.375 mg pramipexole daily to 1.5 mg pramipexole daily over a 6 week period. These patients were then continued on 1.5 mg pramipexole daily for the remainder of the 15 months of the study.
