Figure 2. Adjusted hazard ratios for the composite endpoint myocardial infarction (MI), stroke, or death, in relation to CHADS₂ or CHA₂DS₂-VASc scores, in patients with acute coronary syndrome.

The risk of MI, stroke, or death progressively increased with each unit increase in CHADS₂ and CHA₂DS₂-VASc scores. The reference groups are patients with scores of 0. * And § are defined as p<0.001 vs. CHADS₂ and CHA₂DS₂-VASc scores of 0, respectively.
