Data on partner numbers, condom use and injecting drug use are that reported for the three months preceding the consultation.
p Values for OR: p<0.05*, p<0.01**, p<0.001***.
†The reported mean partner numbers are derived from the raw data, the ORs are derived from recoded data, as described in the ‘Methods’ section.
‡Condom use data and injecting drug use data is binary, being ‘always’ versus ‘not always’ for condom use, and ‘yes’ versus ‘no’ for injecting drug use.
MSM, men who have sex with men; MSW, men who have sex with women.
