Cho/cr = ratio of choling/creatine; mIns/Cr = ratio of myoinositol/creatine; Naa/Cr = ratio of N-acetyl aspertate/creatine Naa/Cho = ratio of N-acetyl aspartate/creatine. General cog = general cognitive ability estimate, Sight word = sight word reading composite, Phono Decoding = phonological decoding composite, ND Comp= Nelson-Denny Test of Reading Comprehension.
