The final sample of n = 19 control participants (10 male) was younger (age: mean = 60.7 ± 9.1; years t = −2.3, p = .03) and showed a trend towards being more highly educated (education: mean = 14.2 ± 3.2 years; t = 1.9, p = .06), which is why education- and age-effects were investigated as potential confounders in all analyses comparing FTLD versus control groups.
