Confusion matrix for assessing correlation between histopathology assessments and the DESI-MS estimates of TCP and disease status of tissue biopsies

Histopathologya
High TCP/Gliomab 		Low TCP/Infiltrative Marginb
Full-scan NAA Intensity TCP Estimate High TCP/Gliomab 91 25
Lipid Deconvolution TCP Estimate 76 15
PCA-LDA Diagnosis 60 18
Full-scan NAA Intensity TCP Estimate Low TCP/Infiltrative Marginb 9 78
Lipid Deconvolution TCP Estimate 24 88
PCA-LDA Diagnosis 35 91
a

Histopathology assessments of TCP were used for correlation with lipid deconvolution and NAA intensity classifications of TCP. Histopathology assessments of disease status were used for correlation with PCA-LDA diagnosis of the tissue smears.

b

For lipid deconvolution and NAA intensity classification, histopathology TCP categories were High = 51% and Low = 50%. Histopathology categories of glioma and infiltrative margin were used for correlation with PCA-LDA diagnosis of glioma and infiltrative margin.
