The relationship between improvement ratings in verbal communication (a, b) and expressive language (c, d) and age for children with (b, d) and without (a, c) binding folate receptor autoantibody. (a, c) For children without the binding autoantibody, improvements in verbal communication and expressive language are higher for older children than for younger children. (b, d) For children with the binding autoantibody, improvements in verbal communication and expressive language are higher for younger children than for older children. Correlation coefficients are provided for the relationship between improvement and age for each graph; hence, the P-value for these correlations are not provided.
