Yes it did.
> We linked the structural brain differences to scores on two cognitive tests taken at the time of the imaging visit: verbal-numerical reasoning and reaction time (see Method). Descriptive statistics for the cognitive tests are shown in Table 1. Note that we coded both tests (reflecting the reaction time variable) so that higher scores indicated better performance. The test scores correlated positively, but weakly (r = .12). Males had a slightly higher mean score than females on verbal-numerical reasoning (d = −0.18) and slightly faster mean reaction time (d = −0.22); there was no significant variance difference for verbal-numerical reasoning (VR = 0.97, P = .45), though males had marginally more variance in reaction time (VR = 0.92, P = .03).
I don't know why they didn't include any graphs for those results.
