a Motor and non-motor characteristics of all patients (black bars: PIL, white bars: no-PIL: all) and subgroups of no-PIL patients with motor fluctuations (no-PIL: mot-fluct; gradient bars), or matched for disease-duration (no-PIL:dis-dur; light gray bars) or age-at-motor-onset (no-PIL: age-ons; dark gray bars). b Characteristics of motor fluctuations in PIL patients compared to those with motor fluctuations in the no-PIL groups. P values represent results of the chi-square or Mann–Whitney test comparing each no-PIL group to the PIL group. Legend: PIL: protein interaction with levodopa, no-PIL: no protein interaction with levodopa, motor fluct: motor fluctuations, behav. OFFs: behavioral OFFs, FOG: freezing of gait, dysk: dyskinesias, ortho.:orthostasis, halluc.: hallucinations
