  1. 3Group results are presented plus minus 2 standard deviations. Right abs: absolute volume of right hippocampus, etc. Rightnorm: normalized volume of right hippocampus, etc. R/L p: significance level of the difference between right and left volumes (paired t test). M/W p: significance level of the differences between.
