*Total n is based on data from six GP practices (one practice did not provide data while another one only provided aggregate data) and is equal to 1821 invited men; missingness for the age band variable was n=21 (1%).
†The reference category for age is the 60-65 years band.
‡The reference category for ethnicity is ‘White’.
GP, general practice; IMD, Index of Multiple Deprivation.
