Mediation models predicting (log +1) PGSI scores

Mediator	Jurisdiction -> mediator	Mediator -> PGSI	Indirect effect	Direct effect	Variance explained
Model 3: EGM participation plus demographics	.	.	.	0.005 (−0.025, 0.036)	0.265***
EGMs	−0.160*** (−0.205, −0.116)	0.320*** (0.289, 0.351)	−0.051*** (−0.067, –0.036)	.	.

Note: Values are standardised coefficients and 95% confidence intervals. *p < 0.05, **p < 0.01, ***p < 0.001. Independent variable was jurisdiction (rest of Australia = 0, WA = 1), and mediator was participating on EGMs within the last 12 months (no = 0, yes = 1).
