Fig. 2

Comparison of genetic and proteomic markers. Genetic markers of gliomas and their relationship to plasma concentrations of the four biomarkers shown (FABP4, GFAP, MMP3, NEFL). The figure shows the median (horizontal lines), and interquartile range. Means are indicated with an ‘x’. Significance levels for independent t tests are shown at the top of each plot and have not been adjusted for multiple comparisons. Despite several differences indicating statistical significance, these differences are generally small. For more details of patient genetic status see also Supplementary Table 5. For GFAP, the most important differences (P = < 0.01) were between GFAP and IDH1 status, ATRX expression, MGMT promoter methylation, TERT promoter mutation, and CDKN2A/B p16 and 1p/19q co-deletion
