Specifically, for AVPA, the odds ratio varied from 0.973 (95%CI: 0.909,1.042, p = 0.436) for dementia to 1.014 (95%CI: 0.961, 1.070, p = 0.618) for CF; for MVPA, the odds ratio varied from 0.882 (95%CI: 0.561, 1.385, p = 0.585) for CF to 1.002 (95%CI: 0.998, 1.005, p = 0.388) for Alzheimer’s disease; for VPA, the odds ratio varied from 0.420 (95%CI: 0.133, 1.328, p = 0.140) for CF to 1.801 (95%CI: 0.344, 9.433, p = 0.486) for dementia (Table 4). This evidence concerns the gene CFTR and early-onset autosomal dominant Alzheimer disease.
