Kallikrein 6 (KLK6) levels between subject groups and association with age in cohort 1. a, b One-way analysis is presented in box plots with individual subjects represented as circles (clear circles = control subjects, red circles = patients with Alzheimer’s disease [AD]). Plasma (a) and cerebrospinal fluid (CSF) (b) levels of KLK6 were compared between control subjects (white box) and patients with AD (red box). c, d Linear correlation analysis between KLK6 values (y-axis) and age (x-axis) for control subjects (left, black correlation lines) and patients with AD (right, red correlation lines). NS Not significant
