Fig. 1: Plasma Aβ values stratified by race and cognitive status.
From: Baseline levels and longitudinal changes in plasma Aβ42/40 among Black and white individuals
Values for plasma Aβ42/40 (A), Aβ42 (B), and Aβ40 (C) are shown for Black (N = 323) and white (N = 1547) participants stratified by cognitive status. The box indicates 50% of the data from the 25% quantile to the 75% quantile, with the horizontal lines representing the median. The individual data points were jittered horizontally for better visualization. The whiskers extend to 1.5 times of the 25% and 75% quantile. Overlaid are individual data points with gray for white participants and red for Black participants. The significance of unadjusted racial differences was evaluated by two-sided Wilcoxon rank sum tests with unadjusted p values reported. Source data are provided as a Source Data file.
