Table 4. Mean Hippocampal Volume and cVEMP by Laterality.
Baltimore Longitudinal Study of Aging (BLSA), 2013–2015. The dependent variables include the mean of right and left hippocampal volume, the right hippocampal volume, and the left hippocampal volume (mm3). All models were adjusted for age, intracranial volume, sex, and race.
