Databases:

A group of 35 adolescents with 15 males and 20 females were included in the study. The Canadian group was from 16 up to 17 years old.


[edit] Results

The researchers use a large cluster threshold on k>200 and only looked in the frontal and limbic regions at an uncorrected level of P<0.001 (one/two-tailed?) (page 600).

Neuroimaging data was also correlated with Pain Catastrophizing Scale (PCS), but the researchers found no supra-threshold clusters found.
