Figure 1 The histograms showed the plasma levels of nitrate/nitrite (upper panel), nitrotyrosine (middle panel), and myeloperoxidase (bottom panel) in randomly selected CC (n = 88) and TT (n = 88) patients. The panels on the left showed all of the cohort; those on the right pertain to the CC (n = 26) and TT (n = 37) patients who were not receiving nitrate for treatment of coronary artery disease (CAD).
