The “Ethics approval” statement in this article has been amended to read:
Ethics approval: The clinical service in this study was provided as an outreach from the Bath specialist CFS/ME service. The North Somerset & South Bristol Research Ethics Committee decided that the collection and analysis of data from children and young people seen by the specialist CFS/ME service as part of service evaluation did not require ethical review by an NHS research ethics committee or approval from the NHS R&D Office (REC reference number 07/Q2006/48).
