Association between strata of transformed UPSIT score and MPS

	Unadjusted logistic regression analysis (MPS = dependent variable)	Adjusted logistic regression analysis^{^} (MPS = dependent variable)

Transformed UPSIT score
Below median	1 (reference)	1 (reference)
At or above median	1.84 (1.33 – 2.57), p < 0.001	1.55 (1.10 – 2.18), p = 0.01

Transformed UPSIT score
Lowest quartile	1 (reference)	1 (reference)
Second quartile	1.35 (0.81 – 2.26 ), p = 0.24	1.24 (0.74 – 2.09 ), p = 0.42
Third quartile	2.02 (1.28 – 3.18 ), p = 0.002	1.74 (1.09 – 2.78), p = 0.02
Highest quartile	2.20 (1.39 – 3.48), p = 0.001	1.67 (1.03 – 2.72), p = 0.04
