Posting CRFs to the correct address

A reminder to all UK and ROI sites:  Please ensure you are posting CRFs to the correct address.  MRC CTU has been based at 2nd Floor, 90 High Holborn, London, WC1V 6LJ since October 2017.  Post going to our old address may not reach us.  CRFs with the correct address at the base can be downloaded and printed from the trial website members area, under ‘current CRFs’.
