Figure 1 Levels of sICAM-1 in ng/ml in UA, NQMI and control groups at four sampling time points. p values refer to differences in levels of soluble ICAM-1 between the three groups. ^#p < 0.05 for levels of sICAM-1 at 6 months versus levels at 12 months in UA and NQMI groups. ICAM-1 = intercellular adhesion molecule-1; NQMI = non–Q wave myocardial infarction; UA = unstable angina.
