a statistical trendP ‐value = 0.083
Regarding PD + MCI versus PD‐NC, three variables were included in the model: MDS‐UPDRS Part III, FiPaT total error, and topography total error; among these, FiPaT total error and topography total error resulted statistically significant ( P ‐value = 0.049 and P ‐value = 0.026, respectively), whereas MDS‐UPDRS Part III showed a statistical trend ( P ‐value = 0.083).
