Figure 3 Mean (95% CI) individual dimensions of the Parkinson's Disease Questionnaire (PDQ)‐39 for patients that remained drug naïve throughout the follow‐up consultations (n = 61) (A). *p<0.01 (mixed ANOVA) between baseline and the second follow‐up in all dimensions. In patients initially drug naïve at baseline but who received anti‐PD drug treatment between the first and second follow‐up consultation (n = 53) (B), there was a trend to worsening between baseline and the first follow‐up in six of the eight dimensions (mixed ANOVA, p>0.05) and thereafter a trend to improvement in six of the eight dimensions (B).
