Data are expressed as medians (25th/75th percentile). The age of the 3 different groups did not differ significantly (p = 0.55, Kruskal–Wallis test)
MCI Mild cognitive impairment, TP-ECLIA Treponema pallidum electrochemiluminescence immunoassay, WB Western blot, na not analyzed
aThe frequency of women with a positive TP-ECLIA was higher than the frequency of women among the patients with a negative TP-ECLIA (p = 0.04, two-sided Chi2 test)
