Comparison of neurological measurements; Unified Parkinson’s Disease Rating Scale motor subscores (UPDRS-III), levodopa equivalent daily dose (LEDD), and dopamine agonist usage, preoperatively and after three months of STN-DBS.

	Preoperatively	Three-month follow-up	Mean differences (SD)	value
UPDRS III off, mean (SD)	48.9 (12.4)	19.8 (9.7)	29.1 (10.7)	<0.01
UPDRS III on, mean (SD)	15.9 (9.4)	12.2 (7.8)	3.7 (9.0)	0.014
LEDD in mg, mean (SD)	1217 (433)	636 (327)	581 (368)	<0.01
Dopamine agonist usage, (%)	37 (92.5%)	18 (45%)		<0.01
