Relative risk for increased carotid IMT according to plasma CTGF N fragment and AER

CTGF N	AER < 40 mg/d	AER > 40 < 299 mg/d	AER > 300 mg/d
High	RR = 1.86 (1.30–2.67)	RR = 2.54 (1.21–5.23)	RR = 4.76 (2.21–10.25)
	n = 376 (P = 0.0007)	n = 41 (P = 0.0135)	n = 36 (P < 0.0001)
Low	RR = 1.00	RR = 2.42 (1.13–5.18)	RR = 2.69 (0.59–12.92)
	n = 415	n = 43 (P = 0.0224)	n = 9 (P = 0.1989)
Total	n = 791	n = 84	n = 45

Increased IMT is defined as the top quartile of distribution for men and women combined. Estimates are age adjusted. RR, Relative risk (95% confidence interval).
