↵a In order to maintain patient anonymity, Diagnostic Imaging Dataset rounds CXR counts for each practice to nearest 5 and counts of <3 are suppressed. In this study ‘2’ was substituted for practices with counts of <3.
↵b The ethnic composition of practice populations estimated by applying 2011 census data to the 2015 practice populations. These estimates were obtained from Public Health England.
↵c As a result of rounding, not all percentages add precisely to 100.
↵d Derived from Index of Multiple Deprivation practice scores for 2015. F1 = least deprived; F5 = most deprived. CXR = chest X-ray. IQR = interquartile range.
