  2. *Numbers do not add up to column total due to missing data; data on symptoms were missing for 9 patients in the Netherlands and data on sexual preference were missing for 3 patients in Suriname. Percentages were calculated based on those with non-missing data and thus add up to 100 %
  3. **In the Netherlands a positive HIV status was based on a positive HIV test in the past or on the date of inclusion (noted in the patient records); a negative HIV status was based on a negative HIV test result on the date of inclusion. The HIV status was unknown when a HIV test was lacking on the date of inclusion. In Suriname the HIV status was self-reported at the date of inclusion
