Box and swarm plots of (A) baseline age, (B) estimated γ, and (C) estimated progression score s at baseline by baseline diagnosis for individuals in the training set. γ and s are plotted on a natural logarithm scale. All pairwise comparisons were statistically significant (all P < 0.0013), with the exception of baseline age comparison between NL and AD. Abbreviations: AD, Alzheimer's disease; MCI, mild cognitive impairment; NL, cognitively normal.
