    Snippet: After ELISA testing, 2597 samples tested positive and were sent to the SZCCC for further examination. Among them, 733 (28.2%) were both TPPA and TRUST positive, 728 (28.0%) were only TPPA positive, and 1136 (43.7%) were false positive (Figure 1) . CI, 1.5-2.2) higher than that among people aged 25-34 years, respectively. Trend analysis showed that the prevalence of syphilis seropositivity (χ 2 trend = 311.9, p trend < 0.001) and active infection.....
    Document: After ELISA testing, 2597 samples tested positive and were sent to the SZCCC for further examination. Among them, 733 (28.2%) were both TPPA and TRUST positive, 728 (28.0%) were only TPPA positive, and 1136 (43.7%) were false positive (Figure 1) . CI, 1.5-2.2) higher than that among people aged 25-34 years, respectively. Trend analysis showed that the prevalence of syphilis seropositivity (χ 2 trend = 311.9, p trend < 0.001) and active infection (χ 2 trend = 72.1, p trend < 0.001) increased significantly with age ( Table 2) . After stratification by gender and year of donation, the increasing trend of prevalence with age remained (p trend < 0.05), except for the prevalence of active infection among males (χ 2 trend = 0.923, p trend = 0.337) and females (χ 2 trend = 0.224, p trend = 0.636) in 2014 (Figure 2 ).
