[Top] Effect of age range harmonization of the mean diffusivity (MD) metric between the modified CamCAN and CamCAN. Green checks indicate correct harmonization, red X’s indicate poor harmonization.[Bottom] Training and testing mean absolute difference (MAD) harmonization error for age ranges from 10 to 70 years of the Modified-CamCAN dataset.
