Table A1.
MRI-GENIE patient cohort. Statistically significant group differences between sites were assessed using ANOVA (age) and χ2 tests (sex and prior stroke). All tests between the individual sites were found to be significant (p < 0.001). For the validation set only prior stroke was found to be statistically significant (p < 0.01), when compared to the remainder of all subjects.
