The original version of this article unfortunately contained a mistake in Fig. 2 caption. (1) The blank section of the bars represents patients with “drooling”; (2) the section with simple lines represents patients with “no excessive saliva”; and (3) the section with crossed lines represents patients with “sialorrhea”.

The correct order would be:

(1) The blank section of the bars represents patients with “no excessive saliva”; (2) the section with simple lines represents patients with “sialorrhea”; and (3) the section with crossed lines represents patients with “drooling”.

The correct caption with Fig. 2 is given in the following page.

Proportion of patients with “sialorrhea” ( ), “drooling” ( ), and “no buccal salivation excess” ( ), as evaluated by the UPDRS Item #6. Differences between non-fluctuators on treatment and fluctuators in the “ON condition” was compared by Chi-sq test. The comparison between fluctuators in the “ON” and “OFF” conditions was performed by McNemar test
