Time frame: Questionnaire completed at a single time-point during the run of the cross-sectional study (16 months). Suitable patients suffer from idiopathic iPD treated with a combination of l-dopa or another oral iPD drug and Neupro® for at least one month.
This individual question from the caregivers' questionnaire was to be assessed from "major disadvantages" to "major advantages", and the corresponding answer was to be evaluated according to a 5-point rating scale using a score from -2 to +2.
Each physician could have assessed one or multiple participants. The scores from each physician were averaged over all participants they assessed, and the final mean score was calculated from the averaged assessments of the physicians.
