Overall P-values for categorical variables were specified by: *P < 0.05 **P < 0.01
^aCalculated by means of multivariable Poisson regression analysis, including provider, age, test year and SES, where appropriate. The rows stating ‘Provider’ should be read horizontally and include the analyses of differences in number of tests between providers. Analyses evaluating differences in number of tests by age, test year and SES were stratified per provider and should be read vertically
^bRange of test years: 2006–2010
^cThe numbers given for the SES categories do not add up to the total number of tests performed, because of missing SES data for a proportion of patients
^d Comparison of Neisseria gonorrhoea testing rates between men and women; men are reference category
