Postmortem interval (h)	4.6 ± 3.4	7.1 ± 7.8
Braak AD stage (median, range)^*	2.0, 0–4	1.0, 0–4
^aCERAD plaque score (median, range)	0, 0–3	0, 0–1
^bPC count^*	31.8 ± 6.4	46.0 ± 12.6
^bAxonal torpedoes^*	13.3 ± 13.9	2.7 ± 2.9
Parallel fiber integrated density	23798.2 ± 16789.7	33515.1 ± 36261.0
Parallel fiber count	11.3 ± 4.2	10.3 ± 4.1

Mean ± standard deviation and frequency (%) are reported unless otherwise specified

p < 0.01, cases versus controls. Student’s t test was used for comparisons of means, Mann–Whitney test was used for comparison of medians, and χ² tests were used for comparison of proportions

CERAD plaque scores were converted from letters to numbers: 0, absent; 1, sparse; 2, moderate; and 3, severe

In each brain, torpedoes in the entire 3 × 20 × 25 mm section were counted, and PCs in five 100× fields were counted and averaged
