The sample median (minimum, 25th percentile, 75th percentile, maximum) is given for numerical variables. LB = Lewy body, NFT = neurofibrillary tangle, SP = senile plaque. Information was unavailable for the following variables: LB count (MF: N=2, ST: N=1, IP: N=3, CG: N=7), NFT count (ST: N=1, IP: N=3, CA1: N=6), Braak NFT stage (N=2), SP count (ST: N=2, IP: N=4, MTR: N=42, VC: N=13), and brain weight (N=25).
