Table 1 Overview table of ATLAS 2.0 dataset with original training dataset, the final dataset used for analysis after excluding n = 14 patients and the subset used for the manual tracing and FreeSurfer segmentation, controlled for the stroke volume, Kolmogorov–Smirnov test: D = 0.152, p = 0.523.
From: Automated hippocampal segmentation algorithms evaluated in stroke patients
