Downton values in total group and each group.

Outcomes measurements	Total group Mean ± SD (range) (n = 124)	Non‐Parkinson’s group Mean ± SD (range) (n = 62)	Parkinson’s disease group Mean ± SD (range) (n = 62)	p‐Value
Downton value	1.98 ± 1.27 (0–5)	1.31 ± 1.19 (0–4)	2.65 ± 0.96 (1–5)	<0.001†

Note: In all the analyses, p < 0.05 (with a 95% confidence interval) was considered statistically significant. Mean ± standard deviation, range (min–max) and † Student's t‐test for independent samples were applied.
