The first group consisted of 106 male Vietnam War veterans who had sustained traumatic brain injuries during combat. These men, aged between 53 and 75 at the time of brain imaging, were part of a long-term study conducted at the National Institutes of Health. The second group included 84 patients from rural Iowa who had experienced brain injuries from various causes, such as strokes, surgical resections, or traumatic head injuries. This second group was more diverse in terms of gender and had a broader range of injury causes.

Are those sample sizes big enough?
