Figure 2

Significant gene ontology categories defining exercise-related changes in control (a) and CFS subjects (b). The three organizing principles of GO (represented as grey shaded boxes) are molecular function, biological process, and cellular component. Related ontologies and/or subgroups of the ontologies are denoted by similarly colored squares in all tables. Ontologies presented in these figures were significant at a p-value <0.005 by one or both of the LS and KS permutation tests.
