CSF sTREM2 levels correlated with age in the control groups. We found a significant positive correlation between age and sTREM2 in the control groups (Spearman rho = 0.50; p < 0.001; n = 75). The regression line (dotted lines representing the 95 % confidence interval) is based on merged data for both cohorts. sTREM2 soluble triggering receptor expressed on myeloid cells 2
