The CSF levels of CCL24 and CXCL7 were both statistically significantly higher in patients with neurosyphilis than in those without (CCL24: 6.082 ± 1.137 pg/mL vs 1.773 ± 0.4565 pg/mL, P = .0037; Figure 2A; CXCL7: 664.3 ± 73.19 pg/mL vs 431.1 ± 90.54 pg/mL, P = .0118; Figure 2C). This evidence concerns the gene CCL24 and neurosyphilis.
