Fig 1. Correlation of punding severity and Parkinson’s disease (PD) duration, PD medication duration, and levodopa-equivalent dose (LED).

Punding severity was significantly correlated with (A) LED (r = 0.69, p = 0.029) and showed a tendency toward an association with (B) PD duration (r = 0.58, p = 0.079). PD medication duration did not show a linear correlation with (C) punding severity (r = 0.52, p = 0.126).
