The Editor of the journal has agreed to a request from the authors that the ethics statement should be changed to improve its clarity. This request was received in October 2019. Due to an internal miscommunication at the publisher the correction was not made. The publisher apologises for this oversight. The new statement is as follows:

‘The North Somerset & South Bristol Research Ethics Committee decided that the original collection and analysis of data from the regional specialist paediatric service was service evaluation and as such 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). In a letter dated 29 January 2007, the Chair of the Research Ethics Committee had previously confirmed (a) that it would not be necessary to apply for ethical permission to use the data being collected as part of service evaluation for the national CFS/ME collaborative and (b) that if in future this data were to be used as part of a research project, this would be agreeable.’
