Multiple linear regression models for log β-thromboglobulin: associations with average pulse wave velocity exposures during the 24-month study

Variable	Parameter Estimate (SE)	P value
Model including Carotid-femoral PWV
Carotid-femoral PWV (cm/s)	0.71 (0.36)	0.054
Leptin (ng/mL)	0.011 (0.005)	0.04
Model including Brachial-ankle PWV
Brachial-ankle PWV (cm/s)	0.0010 (0.0005)	0.03
Leptin (ng/mL)	0.013 (0.005)	0.01

All independent variables are average risk factor exposures over the course of the two year study (area under the curve divided by follow-up time for each subject). β-thromboglobulin and carotid-femoral PWV were log transformed. PWV=Pulse Wave Velocity. The variables considered for inclusion but removed by the stepwise procedure were plasma C-reactive protein and body mass index.
