Each subject in cohorts 1 and 2 was previously matched to a normal comparison subject based on sex and as closely as possible for age and postmortem interval and group matched for handedness. There were no diagnostic group differences in age [t(52) = .517, p = .608] or postmortem interval [t(52) = .584, p = .561] or in the distribution of handedness between diagnostic groups (χ12 = 1.46, p = .314). Mean storage time did not differ between diagnostic groups [cohort 1: t(28) = .040, p = .968; cohort 2: t(22) = .596, p = .557].

A, ambidextrous; ATOD, at time of death; F, female; L, left-handed; M, male; PMI, postmortem interval; R, right-handed; U, unknown.
