FT-IR based ECM3 discrimination model: (a) ECM3 positive pixel fraction (IR Score) in ECM3 and non-ECM3 patients as defined by gene expression analysis; *p-value less than 1.9 × 10−10. (b) IR based ECM3 classification can be performed by assigning ECM3 status to all tumors with IR score above Opt. (c) Linear model fit of expression of core genes of the ECM3 cluster with the IR score.
