  Supplemental Fig. 1.. Flow chart of this study In total, 2,132 consecutive patients who had any histories of ASCVD events and underwent carotid ultrasonography between January 2006 and December 2015 were retrospectively analyzed. Ninety seven patients lacking data (5%) were excluded.

  Fig. 2.. Cumulative event rate divided by carotid plaque score quintile X-axis represents follow-up period (year). Y-axis represents event rate. Red dotted line indicates quintile 5. Green dotted line indicates quintile 4. Black dotted line indicates quintile 3. Blue dotted line indicates quintile 2. Light blue solid line indicates quintile 1.

  Fig. 3.. Receiver-operating characteristic curve The black line (model 1) indicates the receiver-operating characteristic curve using traditional risk factors, including age, gender, hypertension, diabetes, smoking, triglyceride, LDL cholesterol, HDL cholesterol. The red line (model 2) indicates the receiver-operating characteristic curve using traditional risk factors and carotid plaque score.

  Fig. 4.. Plots of correlation between age (X) and carotid plaque score (Y) in male (A) and female (B) patients with ASCVD The regression equations were Y = 0.245X−6.63 (r = 0.50, p < 0.001) in male and Y = 0.189X−6.09 (r = 0.469, p < 0.001) in female.
