  1. Biomarker values were selected as 90th percentile (normal, −) and 10th percentile (abnormal, +); for Tau, 10th percentile was selected as normal (−) and 90th percentile as abnormal (+). Note that this table is an example, as the model can provide individualized risk estimates for any given value. Data are % [95% CI]. For CSF, −/− AB and Tau negative: +/− AB positive and Tau negative; −/+ AB negative and Tau positive; +/+ AB and Tau positive
