Levels of nitrite in WSS correlate with HbA1c. Micromolar concentrations of nitrite were calculated from the standard curve constructed with sodium nitrite as a reference compound. The data are representative of three independent experiments; (*p < 0.05) significantly different between poor glycemic control (> 8% HbA1c) and good glycemic control (< 5.9% HbA1c)
