Hazard ratios for hard and all CHD events for twofold increase in AS and SWCSs
Hard Coronary Event Any Coronary Event
Participants CAC No. Events/No. At Risk Hazard Ratio (95% CI) No. Events/No. At Risk Hazard Ratio (95% CI)
All Log2(AS + 1) 171/6508 1.19 (1.14-1.26) 291/6508 1.25 (1.20-1.30)
Log2(SWCS + 1) 1.23 (1.16-1.30) 1.28 (1.22-1.35)
AS > 0 Log2(AS + 1) 149/3243 1.16 (1.08-1.25) 257/3243 1.24 (1.17-1.31)
Log2(SWCS + 1) 1.18 (1.09-1.27) 1.25 (1.18-1.33)
AS = 0 Log2(SWCS + 1) 22/3265 1.11 (0.79-1.55) 34/3265 1.04 (0.79-1.38)

Each unit increase in Log2(Score+1) represents doubling of CAC. All regressions adjusted for race, age, sex, smoking, diabetes, cholesterol, blood pressure, lipid-lowering medication use, and antihypertensive medication use.
