Identification of urinary and plasma biomarkers in severe pneumonia cases.

Biomarkers that exhibit significant differences between controls and pneumonia samples as determined through SIMCA-P+ and Random Forests. Markers 1–7 have been verified through tandem mass spectrometry (MS/MS) against pure chemical standards. Markers 8–15, although were determined as of high importance through the multivariate data analysis, were also tested against pure chemical standards, but were not verified as such.
