  1. Footnote: Differential abundance was denoted by greater than or equal to ± 2.0-fold change; p ≤ 0.05; protein identified by at least two unique peptides.  Positive numbers denote higher abundance in non-responders than in responders. Proteins were identified using either protein dynamic compression coupled with label-free quantitation LC-MS/MS or no protein dynamic compression with isobaric tags for absolute and relative quantitation (iTRAQ) LC-MS/MS
