TABLE 1:
Analysis of significant differences between tumor groups at TE 30
| Pairwise Comparisons | Resonances Showing Significant Differences† |
||
|---|---|---|---|
| P* < .001 | P* < .01 | P* < .05 | |
| MEN vs LGA | GLX | Ala | Gly/MI |
| MEN vs AA | Ala | CR | |
| MEN vs GBM-MET | LIP09, LIP13, Ala, GLX, CR, CHO, Gly/MI | ||
| LGA vs AA | |||
| LGA vs GBM-MET | LIP09, LIP13, CR, Gly/MI | ||
| AA vs GBM-MET | LIP13, CR, CHO | LIP09, Gly/MI | |
Note.—Differences of P corrected values (P*) <.05 were considered to be statistically significant. MEN indicates meningioma; LGA, low grade astrocytoma; AA, anaplastic astrocytoma; GBM-MET, glioblastoma-metastasis group; GLX, glutamate and glutamine; Ala, alanine; LIP, lipid; CR, creatine plus phosphocreatine; CHO, choline and other thmethylamine-containing compounds; Gly/MI, glycine and/or myo-inositol.
†
Only the seven resonances showing significant differences in the previously applied Kruskal-Wallis test for multiple samples were considered (LIP09, LIP13, Ala, GLX, CR, CHO, and Gly/MI).
