Selected clusters of similar biologic functional terms for genes, the expression of which differed between untreated patients with polymyalgia rheumatica (PMR) and non-PMR control subjects. The clusters and the enrichment scores (the geometric means of the EASE scores [24] of all terms in the cluster) were derived using the Database for Annotation, Visualization and Integrated Discovery (DAVID) tool [23]. Green squares denote that the gene/term association has been positively reported; black squares denote that the gene/term association has not yet been reported. a Cluster with an overall theme of translation/protein biosynthesis and with an enrichment score of 0.8. b Cluster with an overall theme of (nuclear) protein transport associated processes and with an enrichment score of 0.83. c Cluster with an overall theme of gene expression/transcription regulatory processes and with an enrichment score of 0.69
