Associations among copeptin, TRV, and 24-hour UAE as markers of disease severity in ADPKD

Model	Adjusted for	TRV		UAE
		Standardized β	P	Standardized β	P
1	Crude	0.47	<0.001	0.39	<0.001
2	As 1 + age and gender	0.34	0.001	0.42	<0.001
3	As 2 + use of diuretics	0.33	0.001	0.44	<0.001
4	As 2 + GFR	0.23	0.05	0.26	0.04

Independent variable is log copeptin. Dependent variables are log TRV and log albuminuria. A positive standardized β indicates that a high copeptin concentration is associated with a high TRV or UAE, respectively.
