Gene Ontology categories identified as significantly different between controls and CFS cases at baseline (pre-exercise) (a) and post-exercise (b). The three organizing principles of GO (represented by grey shaded squares) 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.
