Fig. 3From: CSF synaptic protein concentrations are raised in those with atypical Alzheimer’s disease but not frontotemporal dementiaCorrelation matrix displaying the Spearman correlation coefficients between CSF protein concentrations for each of the synaptic measures (Ng22, Ng36, SNAP-25tot, SNAP-25aa40, and synaptotagmin-1), for patients (i.e. controls not included). The gradient scale bar represents the strength of the correlation; the purple darkens as the correlation approaches a value of 1. Italicised coefficients represent biomarkers which were not significantly correlated (only Ng36 with synaptotagmin-1)Back to article page
