Figure 2

Comparison of values for moderate positive AQP4 ELISA in patients meeting the criteria for NMOSD versus those with other diagnoses. (a) Distribution of values for each group. Patients with multiple tests were averaged to give one test value per patient (3 patients in the NMOSD group). The large labeled data point is the median for the group. (b) Mean assay values for each group. Error bars represent the standard deviation; . NMOSD: neuromyelitis optica spectrum disorders.
