*Opposite and/or same-sex partners.

†Defined as two or more partners in the past year and not used a condom in the past year.

‡Overlap between any of three most recent partners in the past  year.

§Includes partners acquired when abroad and when in the UK.

¶Denominator is smaller for some analyses due to missing data: 10 women had missing data for number of partners, 1 for same-sex partners, 6 for unsafe sex, 139 for concurrency and 51 for partners' concurrency.

GP, general practice; GUM, genitourinary medicine; RRR, unadjusted relative risk ratio for testing in GP/other settings, compared with testing in GUM; unwt, unweighted denominator; wt, weighted denominator.
