Linear mixed-effects regression on deviation from optimal scores across all subjects

Coefficient (intercept)	β estimate (SE)	t-value
Coefficient (intercept)	0.09 (0.43)	0.21
Environment type	−0.01 (0.07)	−0.08
Group	0.72 (0.37)	1.94
PSS	−0.07 (0.03)	−2.90**
Log cortisol Δ	−0.74 (0.36)	−2.04*

PSS and log cortisol Δ scores are in natural (untransformed) units.

***p < 0.001;

**p < 0.01;

*p < 0.05.
