PLS loadings in the initial sets of variables

				PLS loading
X space:
	FA left arcuate fasciculus			0.66 ± SD 0.006
	FA right arcuate fasciculus			0.78 ± SD 0.009
Y space:
	Linguistic skills			0.71 ± SD 0.003
	Cognitive skills			0.71 ± SD 0.002

Showing the PLS loadings of involvement in the identified link between the left and right arcuate fasciculus microstructure, and linguistic and cognitive performance. Mean PLS loadings of involvement ± SD averaged across folds. The PLS mode accounted for 72 and 71% of variance, respectively, in X and Y space. The small SDs of the estimated PLS loadings highlight strong model stability
