Figure 2

The arteriovenous ratio (AVR) in the right eye and left eye for healthy subjects and for those who experienced a myocardial infarction (MI) at a young age (<50 years). The AVR was not significantly different between groups in either the right eye (mean of differences = 0.002; p = 0.85) or the left eye (mean of differences = −0.005; p = 0.56). Statistical significance was tested using a paired t-test. Vertical columns represent 25–75% percentile with indicated mean and error bars represent 10–90% percentile.
