Mean	N/A	63.84	N/A	3.32 (III = 3, IV = 4, V = 5)	71.42	0.74	N/A

Mean values are listed for Hoehn-Yahr and UPDRS-III scores. As a result of lack of regular health care, a few patients have very short disease durations that are inconsistent with the stage of PD because of late diagnosis or diagnosis at the time of the study. Therefore, mean values were not calculated for disease duration.
