^a Class I: combined mutational spectrum of the tumor types for which H0 is rejected in comparison of synonymous vs. non-synonymous substitutions:brain, liver, lung, colon, mouth, larynx, ovary and skin.

^b Class II: combined mutational spectrum of the tumor types for which the test did not find enough evidence, probably, because of the small sample size: bladder, breast, prostate, esophagus, colorectal, hematopoietic, stomach, and pancreas.

^c Class III: combined Class I and Class II spectra.

Other designations are as in Table 1.
