ES, early syphilis; Ref, reference group; CTGC, Chlamydia trachomatis/Neisseria gonorrhea;

^#HIV negative is the reference group unless otherwise stated.

^@Demographics adjusted for age (ordinal categorical) and race/ethnicity (nominal categorical). CTGC testing was adjusted for age, race/ethnicity, and the number of CTGC tests performed (ordinal categorical).

^*Positive test in the 4-week window surrounding the date of ES diagnosis.

^**p<0·001 by ANOVA.
