Selected Baseline Characteristics of the Study
Population (n1952)

3
Changes in Plaque Characteristics Between
Baseline and Follow-Up

4
Plaque Growth (mm2) by Quintiles of Risk Factor
Level at Baseline
S.H. Johnsen, Circulation. 2005 112 498-504
5
Plaque growth in quintiles of HDL
cholesterolValues are age-and sex-adjusted
HDL cholesterol levels in quintiles were lt1.16,
1.16 to 1.36, 1.37 to 1.54, 1.55 to 1.83, and
gt1.83 mmol/L

6
Plaque growth by changes in echogenicityChange
in echogenicity is measured as GSM Values are
age-and sex-adjusted
GSM values in quartiles were less than 9, 9 to 6,
7 to 21, and 21. Negative values indicate plaques
have become more echolucent positive values
indicate plaques have become more echogenic
