PPVT, RDLS scores are in age equivalents. PBK, BIT scores are in percent correct. For each predictor, standardized coefficient (β), t value, and p value are listed. For each model, adjusted R2 is listed. In models with multiple predictor variables, listed R2 reflects the combination of both variables.
