*For chlamydia, gonorrhoea, syphilis and HIV, N=women with a recorded test for the STI of interest; for abnormal cell cytology, N=women with a recorded smear test; and for all other STIs/conditions without a SHAPPT code for the relevant diagnostic test/investigation, N=all women.

‡Code suffixes to identify oral or rectal chlamydia infections were introduced to GUMCAD in 2011. However, as the use of these suffixes was not consistent across all clinics in 2011, the data presented here includes all chlamydia infections. In future, it will be possible to provide information on the site of infection.
