Overall significance of correlations between FA and IQ scores
| FDR valuesa | |
|---|---|
| Verbal IQ | 1.00 |
| Information | 0.67 |
| Arithmetic | 1.00 |
| Vocabulary | 1.00 |
| Performance IQ | 0.01 |
| Spatial | 0.13 |
| Object assembly | 0.007 |
| Full-scale IQ | 0.04 |
FDR < 0.05 (presented in bold font) indicated that 5% of the voxels in which FA was found to be associated with the IQ score are in fact false positive findings. In other words, 95% of the associations labeled are true. The maps of negative correlations between each of these measures and FA were not significant.
aFDR was computed only in regions where the individual IQ score correlated positively with FA.
