Figure 4. Superior prognostic power of iCG compared with random gene signature.

Figure 4

The yellow histogram shows the distributions of the Wald statistic (Z) for the 1,000 resampled gene signatures picked up from human genome with identical size as iCG. The blue histogram shows the distributions of the Z for the 1,000 resampled gene signatures selected from the glioma-associated genes. The black triangles stand for the Z values of iCG. Right-tailed P-values of the sampling distribution were calculated.
