Extended Data Table 4.
Continuous values are presented as the median with the IQR. The significance of differences by amyloid PET status was evaluated with Wilcoxon’s rank-sum tests for continuous variables and χ2 or Fisher’s exact test for categorical variables. The fold difference is the median biomarker value in the amyloid PET-positive group divided by the median value in the amyloid PET-negative group. All tests were two sided and not adjusted for multiple comparisons.
