Figure 1. Hippocampal volumes adjusted for total intracranial volume (HVa) in patients with mild cognitive impairment (MCI).

HVa in patients with MCI who did not progress to Alzheimer disease (AD) or dementia with Lewy bodies (DLB), patients with MCI who progressed to DLB, and patients with MCI who progressed to AD during follow-up. Dark circles indicate those labeled as having abnormal HVa for the survival analysis.
