The Bonferroni-corrected post hoc pairwise comparison demonstrated that the AD group (M = 29.0 ng/L, SD = 21.6 ng/L) had significantly higher levels of NFL compared to controls (M = 18.8 ng/L, SD = 7.2 ng/L; P = 0.025) but not to MCI (M = 20.5 ng/L, SD = 8.1 ng/L; P = 0.096, Fig. 2c). The gene discussed is NEFL; the disease is Alzheimer disease.
