Power curves displaying replication sample sizes required (x-axis: Log-scale N) to achieve desired level of power (y-axis) based on performance of each imaging measure in predicting general cognition in replication sample using (A) multivariate vs (B) univariate methods. Abbreviations: SA, surface area; CT, cortical thickness; RND, restricted directional diffusion within superficial white matter; RNI, restricted isotropic diffusion intracortically; ENb, emotional N-back task fMRI, reflecting the 2- vs. 0-back contrast; RS, resting state fMRI.
