Table 2.

TGN identification rate (percentage of successfully identified TGNs) of the overall TGN and its subdivisions using the proposed automated identification method (highlighted in gray) and the manual selection method. For the PPMI data, we did not perform manual TGN identification; thus, the TGN identification rate was not reported.
