Association with second‐grade reading using stepwise regression analysis to identify the best set of predictors, which includes the combination of pre‐literacy, parental, and FA measures, as well as the FA × maternal education interaction term. (a) and (b) show final prediction models for lower and higher‐SES groups. Actual values versus predicted are plotted, with predicted varying in size. (c) and (d) are the relative importance bar plots with 95% bootstrap confidence intervals for left ILF and right ILF, respectively. Tract names and behavioral measures are abbreviated as follows: PA, phonological awareness; EdMom × LILF or EdMom × RILF, interaction term between maternal education and left or right ILF FA (mean FA of significant nodes); RAN, rapid automatized naming
