^aCMIA, chemiluminescence immunoassay; TPPA, Treponema pallidum particle agglutination; RPR, rapid plasma reagin; Pos, positive; Neg, negative; NR, nonreactive; N/P, not performed; N/A, not applicable (syphilis serology was assessed as negative due to a nonreactive CMIA, or serology that was reactive but unchanged from a previous test result).

^bSyphilis serology assessed as positive or negative based on previous results.
