Serum nitrite levels. Nitrite concentrations were assayed in sera of ALS patients and controls at both visits using a Griess Reagent System. Nitrite levels were higher in ALS sera than control sera on both visits, but the differences were not statistically significant (p = 0.09). Results are plotted as mean ± SEM. Statistical significance was determined using two-tailed t-tests (* p < 0.05, ** p < 0.01)
