SECONDARY outcome
Timeframe: For L-dopa 35 mg, 70 mg, 140 mg, assessment occurred at pre-dose, 15, 30, 45, 60, 90 and 120 minutes post-dose. For L-dopa 70 mg/carbidopa 7 mg, assessment occurred at pre-dose, 30, 60, 90 and 120 minutes post-dose.Population: All participants were analyzed.
MDS-UPDRS is a clinimetric assessment of subjective and objective symptoms and signs of Parkinson's disease created by the Movement Disorder Society with high internal consistency. MDS-UPDRS retains the four-scale structure with a reorganization of the various subscales. The subscale used in this study is Part III, motor examination (18 items). The subscale has 0-4 ratings, where 0 = normal, 1 = slight, 2 = mild, 3 = moderate, and 4 = severe. Maximum score is 132, minimum is zero. High score means worse outcome. For the L-dopa 35 mg, L-dopa 70 mg, L-dopa 140 mg treatment groups, assessment occurred at pre-dose, 15, 30, 45, 60, 90 and 120 minutes post-dose. For the L-dopa 70 mg/carbidopa 7 mg treatment arm, assessment occurred at pre-dose, 30, 60, 90 and 120 minutes post-dose.

SECONDARY outcome
Timeframe: For L-dopa 35 mg, 70 mg, 140 mg, assessments were made at pre-dose, 15, 30, 45, 60, 90, 120 minutes post-dose. For L-dopa 70 mg/carbidopa 7 mg, assessments were made at pre-dose, 50, 60, 90, 120 minutes post-dose.Population: All participants were included in the analysis
MDS-UPDRS is a clinimetric assessment of subjective and objective symptoms and signs of Parkinson's disease created by the Movement Disorder Society with high internal consistency. MDS-UPDRS retains the four-scale structure with a reorganization of the various subscales. The subscale used in this study is Part III, motor examination (18 items). The subscale now has 0-4 ratings, where 0 = normal, 1 = slight, 2 = mild, 3 = moderate, and 4 = severe.

MDS-UPDRS is a clinimetric assessment of subjective and objective symptoms and signs of Parkinson's disease created by the Movement Disorder Society with high internal consistency. MDS-UPDRS retains the four-scale structure with a reorganization of the various subscales. The subscale used in this study is Part III, motor examination (18 items). The subscale now has 0-4 ratings, where 0 = normal, 1 = slight, 2 = mild, 3 = moderate, and 4 = severe. The total of the subscales has a maximum value of 132 and a minimum value of zero. Lower scores indicate better motor function. A negative change from baseline indicates improved motor function.
