Overall number naming MADER regressed on different participant and pain characteristics using two stepwise regression analyses.

Predictor	β	SE	Standardized β	t	p
Participant characteristics and cognition
IQ	−0.045	0.013	−0.352	−3.422	<0.01
Group	0.720	0.266	0.278	2.707	<0.01
Gender	0.663	0.282	0.222	2.353	<0.05

The upper panel shows results of the regression within both groups. Overall model fit: R² = 0.325, Adjusted R² = 0.298. The lower panel shows results of the regression analysis within the chronic pain sample. Overall model fit: R² = 0.161, Adjusted R² = 0.137.
