Correlation coefficient (Pearson correlation) between fractional anisotropy (FA) along white matter tracts and the postmenstrual age before and after harmonization. Locations: 100 planes along the white matter tract. Red and blue dots represent significant (P < 0.05) correlation before and after harmonization, respectively. Note: dual generative adversarial networks are performed with the 2-dimensional kernel on axial slices. Correlation coefficients after harmonization have been averaged over different runs of the sixfold cross-validation. The P ≥ 0.05 in any run of the cross-validation indicates that the correlation is not statistically significant
