Tear data for each cytokine and collection method are standardized to have a mean of 0 and standard deviation of 1. This allows an equivalent determination across all cytokines of the ability to differentiate AD patients from non-AD using NS tear samples (filled symbols) and WO samples (open symbols). Cytokines are ordered on the x-axis by Z score difference between AD NS and normal NS tear samples.
