Gastrointestinal Dysfunction Impact on Life Quality in a Cohort of Russian Patients with Parkinson’s Disease I-III H&Y Stage

Table 2

Generalized linear model coefficients for PDQ-39 SI on both gastrointestinal assessments (GSRS and GDSS).

Model; dependent variable: PDQ-39 SI		Unstandardized coefficients		Standardized coefficient	t		95.0% CI for B
		B	SE	β			Lower	Upper
1	Constant	16.044	2.012		7.975	≤0.001	12.048	20.040
	GSRS-SI	0.708	0.124	0.522	5.701	≤0.001	0.462	0.955
	GDSS	0.779	0.400	0.178	1.947	0.055	−0.016	1.575

Bold indicates values of the regression equation for predicting the dependent variable from the independent variable; SE: standard error; β: beta; t: t-value; : 2-tailed value (significance level); CI: confidence interval.
