Funding
The REACT study was funded by the National Institute for Health Research (NIHR) – Public Health Research Programme (13/164/51). The views expressed are those of the author(s) and not necessarily those of the NIHR or the Department of Health and Social Care. The study was generously supported by the Clinical Research Network at each site. The funder approved the study design but had no role in data collection, data analysis, data interpretation and publications related to the REACT study dataset. The corresponding author was funded by a University of Bath PhD studentship.
