Fig. 6

Representative scatter plot that results from the support vector machine analysis for top ranked cytokine IL-12. Red + indicates non-sensitizer (NS) treatments (untreated, vehicle, and salicylic acid (SA)) and green + indicates sensitizer (isoeugenol (IE) and p-phenylenediamine (PPD)) treated conditions. The line separating the two classes in this plot indicates the center of the margin distance boundary. The two encircled points near the margin distance center boundary indicates the critical points that are used as support vectors. IL-12 data analyzed by the SVM classifier included all treatment conditions (untreated, vehicle, SA, IE, and PPD) and all of their respective concentrations for N = 3 independent replicates.
