  1. athe three models estimate associations in three groups:
  2. uHIVinc – undiagnosed HIV in a group of men reporting a last negative HIV test result within the previous 12 months
  3. uHIVunk – undiagnosed HIV in a group of men who never tested for HIV or whose last negative HIV test result is older than 12 months
  4. uHIV – undiagnosed HIV in the combined group of men irrespective of the time of the last negative HIV test
