Variable	1N/2Mean	Coefficient	p-value
1Current smokers	58	1.6 (1.4)	0.25
1Ex-smokers	270	−0.7 (1.2)	0.56
1History of ischemic heart disease	75	−0.2 (1.5)	0.90
1Diabetes	17	−1.6 (2.8)	0.56
1Peripheral vascular disease	95	−0.4 (1.3)	0.75
2Total cholesterol	5.85	0.35 (0.49)	0.71
2LDL cholesterol	1.15	−0.06 (0.57)	0.92
2HDL cholesterol	3.86	2.57 (1.76)	0.15
2Cotinine	82.1	0.00 (0.00)	0.81
2PIIINP	3.68	−0.20 (0.39)	0.60

note: The number of subjects are classified positive for that variable. Mean values of total cholesterol, LDL-, and HDL-cholesterol in the study population are in mmol/L, and serum cotinine and PIIINP in μg/L.

Abbreviations: PIIINP, amino-terminal propeptide of type III procollagen; N, number; LDL, low-density lipoprotein; HDL, high-density lipoprotein.
