ROC analysis to evaluate CSF protein classification of AD by race. A YWHAB, PPIA, GAPDH, and SPP1 had similar performance in classifying Caucasians and African Americans with AD B SMOC1, LDHB, PKM and ALDOA showed modest improvement in the AUC for Caucasians with AD compared to African Americans with AD C VGF, SCG2, and NPTX2 were better classifiers for AD in African Americans compared to Caucasians, whereas NPTXR showed modest improvement in classification of AD in African Americans. All protein AUCs with p-values and confidence internals (CI) are provided in Supplemental Table 15
