For resistin, the cut-off value was ≥3.8 ng/mL, the sensitivity and specificity for AD were 96.3% (95% CI: 81.0−99.0) and 52.17 (95% CI: 36.9–67.1), and for visfatin the cut-off value was ≤2.13, the sensitivity and specificity were 92.59% (95% CI: 75.7–99.1%) and 97.83 (95% CI: 88.5–99.9%) (Figure 1). The gene discussed is NAMPT; the disease is Alzheimer disease.
