Figure 1.
Receiver operating characteristic (ROC) curve analysis of line immunoassay (LIA) and particle-based multi-analyte technology (PMAT) against immunoprecipitation (IP) as binary classifier. Very high level of discrimination between IP positive and negative samples was observed for PMAT system for (a) PL-7, (b) PL-12, (c) SRP, (d) NXP2, (e) Mi-2, (f) SAE, (g) EJ, (h) MDA5, and (i) TIF1γ. LIA results are expressed as grading values (0 = negative, 1–3 = positive according to instructions for use).
