Percentages shown are row percents. For participants who underwent testing more than once in a single calendar year and had both reactive and non-reactive results, we classified their results as reactive. P-values for calendar year time trends were calculated using logistic regression with GEE.
(a) Acute reactive results were defined as a reactive trepomenal test and RPR titre greater than or equal to 1:16.
