*: Pathways with two or less genes on the microarray. Two genes are not located on a single biochemical route.

**: Pathways with more than two genes on the microarray, but the genes on the microarray are spread over the pathway

***: Pathways with more than two genes on the microarray and the genes are clustered together on a (sub)pathway

****: Many genes of the pathway have microarray information
