did not reach statistical significancep = 0.3827
Comparing all R/E pairs using a Tukey–Kramer multiple comparison indicated that the difference in p-Tau 217 results were among the largest between white and black/AA participant groups, but these differences did not reach statistical significance for either the amyloid positive subjects (mean difference 0.033 pg/mL, p = 0.3827) or the amyloid negative subjects (mean difference 0.013 pg/mL, p = 0.1137) ( Supplementary Table S5 ).
