  1. Data are presented as described in Table 3, that is, relative to creatine. In all cases, the differences between control and RBT were not statistically significant.
  2. Abbreviations: mI, myo-inositol; NAA, N-acetyl aspartate; RBT, repetitive brain trauma; tCho, total choline. In bold are the proton groups that give rise to the crosspeak chemical shifts indicated in the third column.
