  • The average between measurements refers to the average of the mean of both repeated measurements.

  • The mean difference refers to the average difference of the repeated measurements.

  • Variability refers to the standard deviation of the differences between repeated measurements.

  • AHW, anterior horn width; TOD, thalamo-occipital distance.
