Table 2 Demographic and clinical characteristics of the TREM2 coding variants and control (CV) groups. n.i.- no information, ROI- Region of interest. Case#3, with highest fixation time, was omitted for the plaque count and size quantification as it was difficult to define boundaries of extracellular plaques stained with 1E4E11 (pSer8-Aβ) antibody
