SHR for PDD in the patients without diabetes according to glucose variability (CV).

	Model 1*	Model 2**
	SHR (95% CI)	p value	SHR (95% CI)	p value
quartile 1	1 (ref)		1 (ref)
quartile 2	1.18 (0.96–1.45)	0.120	1.18 (0.96–1.45)	0.120
quartile 3	1.21 (0.98–1.49)	0.084	1.20 (0.97–1.49)	0.088
quartile 4	1.47 (1.19–1.82)	<0.001	1.46 (1.17–1.83)	0.001

*Model 1 was adjusted for age, sex, presence of hypertension and hyperlipidemia, heavy alcohol consumption, smoking, and regular exercise in the Fine and Gray competing regression model, including glucose variability as a separate predictor and death as a competing risk.

**Model 2 was adjusted for all covariates in model 1 plus systolic BP, diastolic BP, fasting glucose, total cholesterol, and BMI at index health examination in the Fine and Gray competing regression model.

SHR, subdistributional hazard ratio; PDD, Parkinson’s disease dementia; CV, coefficient of variation; BP, blood pressure; BMI, body mass index.
