Figures & data

Table I. Baseline characteristics of the patients with and without completed follow-up.

	Follow-up completed (n=405)	Lost at follow-up (n=308*)
Age, years (mean ± SD)	55.3 ± 8.7	52.1 ± 11.3
Men, n (%)	175 (43.2%)	161 (52.3%)
Women, n (%)	230 (56.8%)	147 (47.7%)
Risk factors, n (%)
Family history of CVD	35 (8.6%)	37 (12.0%)
Smoking	88 (21.7%)	97 (31.5%)
Obesity (BMI >30 kg/m^2)	94 (23.2%)	63 (20.5%)
Diabetes mellitus	28 (6.9%)	26 (8.4%)
Diagnosis of hypertension*	164 (40.5%)	99 (32.1%)
Total cholesterol, mmol/l (mean ± SD)	6.2 ± 0.7	6.0 ± 0.9
Global CVR, % (mean ± SD)	11.3% 7.2%	9.9% 6.3%

Significant difference for all variables: p < 0.05.* BP ≥ 140/90 mmHg and/or anti-hypertensive drug treatment.CVR: global cardiovascular risk (probability of CV events in 10 years).
