  • *Values of IL-10 have been log transformed and RPR square-root transformed.

  • †Comparison group is those with repeat syphilis at baseline visit.

  • ‡HIV coded as 0=negative, 1=positive.

  • §HIV viral load in copies per millilitre. Continuous variable log transformed.

  • ¶Presence of Neisseria gonorrhoeae or Chlamydia trachomatis at baseline visit. Coded 0=both absent, 1=either present.

  • IL, interleukin; RPR, rapid plasma reagin.
