Correlations in the clinical CSF cohort consisting of young (n = 5), cognitively unimpaired Aβ negative (CU−, n = 15), cognitively unimpaired Aβ positive (CU+, n = 10), cognitively impaired Aβ negative (CI−, n = 12), and cognitively impaired Aβ positive (CI+, n = 28) between the two SNAP-25 forms, SNAP-25 [Long] and SNAP-25 [Total], quantified with MS and SNAP-25 [Simoa] with equation of slope, Spearman’s rank correlation coefficient (rs) and p-value. A SNAP-25 [Total] versus SNAP-25 [Simoa], B SNAP-25 [Long] versus SNAP-25 [Simoa], and C SNAP-25 [Total] versus SNAP-25 [Long]
