Kallikrein 6 (KLK6) association with total apolipoprotein E (apoE) levels assessed in cohort 1. a, b Scatterplots showing associations between plasma and cerebrospinal fluid (CSF) KLK6 with total apoE in respective fluids. Subjects were grouped according to their APOE genotypes, and normal ovals were drawn to represent the area covering the central 50% of the subjects in that group. Red oval = APOE ε4/ε4 genotype, blue oval = APOE ε3/ε4, green oval = APOE ε3/ε3, black oval = APOE ε2/ε3. Clear dots = control subjects, red dots = subjects with Alzheimer’s disease
