Overview of methods and data analysis. Data processing strategy. The combined dataset was generated by separate pre‐processing and normalization of proteomic datasets, followed by data pooling and selection of proteins measured in at least 25% of participants, of whom at least 50 were amyloid abnormal. For detailed description of the data processing strategy, see Methods; for detailed information of which peptides or protein measurements in each study were used for the pooled protein scores, see Table S1.
