†HIV testing is not a standard procedure for TB patients in the Netherlands. HIV infection is recorded in the National Tuberculosis Register as one of the response options of the item "impaired immunity." Considered as HIV infected were those cases with a record of impaired immunity due to HIV infection; all others were classified as HIV status unknown.
