Table 2 Illustrating the diagnostic accuracy of the assessors for particular disease groups when examining the simulated biopsies from the frontal lobe, the temporal lobe and combined

From: Simulated surgical-type cerebral biopsies from post-mortem brains allows accurate neuropathological diagnoses in the majority of neurodegenerative disease groups
