Timetable of the PREVEND study variables used in the analyses presented here

Variables	Time of Measurement
Variables	Baseline Survey (1997 to 1998)	Third Survey (2003 to 2006)
Cognitive function test		RFFT
Renal	Albuminuria	Albuminuria
		Change in albuminuria^{^a}
	eGFR	eGFR
		Change in eGFR^{^b}
		Plasma creatinine
Demographic		Age
		Educational level
Cardiovascular		Diabetes mellitus
		Hypertension
		History of cardiovascular disease
		Body mass index
		Alcohol use
		Cholesterol
		Smoking

↵a Change in albuminuria = albuminuria at third survey minus albuminuria at baseline survey. PREVEND, Prevention of Renal and Vascular End-Stage Disease; RFFT, Ruff Figural Fluency Test; eGFR, estimated GFR.
↵b Change in eGFR = eGFR at third survey minus eGFR at baseline survey.
