Title using 'very large' does not come from the article, which gives a more subtle image:
>Sex Differences in the Adult Human Brain: Evidence from 5216 UK Biobank Participants
>Males had higher raw volumes, raw surface areas, and white matter fractional anisotropy; females had higher raw cortical thickness and higher white matter tract complexity. There was considerable distributional overlap between the sexes.
Personally I wouldn't call the difference between a mean of 1115.76 with an standard deviation of 89.68 and a mean of 1233.58 with an SD of 98.31 very large (all in cm^3)
