In the population-level of analysis, a subset of AA and white AD patients had laboratory values for ESR (AA, n = 832; white, n = 2048), CRP (AA, n = 592; white, n = 1398), ferritin (AA, n = 737; white, n = 1312), and eosinophils (AA, n = 4573; white, n = 9984). Here, CRP is linked to Alzheimer disease.
