A comparison of plaque hyper-intensity (in plaque to myocardium signal intensity ratio (PMR)) between different severities of coronary artery disease. Results are expressed as a box and whisker diagram with minimum, first quartile, median, third quartile, maximum and all individual data points. A progressive increase in PMR was observed among patients with stable angina, unstable angina, non-STEMI, and STEMI (p = 0.004, ANOVA). Post hoc tests showed PMR values of STEMI group was significantly higher than stable angina group (P = 0.007) (*) and unstable angina groups (P = 0.006) (**). However, it has not reached statistic differences between other groups
