Figure 1.

Correlation of HDL cholesterol, HbA_1c and markers of platelet activation. Correlation coefficient (r) for different platelet markers (mean platelet volume, platelet distribution width, fraction of reticulated thrombocytes and multiple electrode aggregometry), HDL cholesterol and HbA_1c. A consistent negative correlation is observed for HDL cholesterol and markers of platelet activation (left column), while only a weak to moderate correlation is found between HbA_1c and platelet function (right column)
