* Active syphilis implies that the antibody titer with the VDRL test was ≤ 1/8 and the TPHA was positive, while positive serology for syphilis implies that the VDRL test was not reactive or < 1/8 and TPHA was positive.
** Positive serology for hepatitis B was assessed by the detection of antibodies to the hepatitis B core antigen (anti-HBC) indicating previous infection.
