*p Values of differences in scores of patients in different H&Y stages; †a significant trend indicates that the trend differs significant from zero—that is, no trend; ‡goodness of fit: p>0.05 indicates that the model does not differ significantly from a model with a good fit; §R-sq: proportion of the variance accounted for by the model.
