TABLE 2:
Analysis of significant differences between tumor groups at TE 136
| Pairwise Comparisons | Resonances Showing Significant Differences† |
||
|---|---|---|---|
| P* < .001 | P* < .01 | P* < .05 | |
| MEN vs LGA | Ala, GLX | CHO | |
| MEN vs AA | Ala | GLX | |
| MEN vs GBM-MET | LIP09, LIP13, LACT, Ala, GLX, CHO | NACC | |
| LGA vs AA | |||
| LGA vs GBM-MET | LIP09, LIP13 | LACT, CR | |
| AA vs GBM-MET | LIP09, LIP13, CR | NACC, CHO | |
Note.—Differences of P corrected values (P*) <.05 were considered to be statistically significant. MEN indicates mengingioma; LGA, low grade astrocytoma; AA, anaplastic astrocytoma; GBM-MET, glioblastoma-metastasis group; Ala, alanine; GLX, glutamate and glutamine; LIP, lipid; CHO, choline and other trimethylamine-containing compounds; CR, creatine plus phosphocreatine; NACC, N-acetyl-containing compounds; LACT, lactate.
†
Only the eight resonances showing significant differences in the previously applied Kruskal-Wallis test for multiple samples were considered (LIP09, LIP13, LACT, Ala, NACC, GLX, CR, and CHO).
