Table 4 Cumulative link mixed model analysis results

Fixed-effects		Coefficient	Standard error	p-value
Simulation type	Mid-face	−2.99	0.79	<0.001
	Peripheral	−1.31	0.75	0.08
	Exaggerated	−7.37	1.09	<0.0001
Gender	Female	−0.15	0.33	0.64
Random-effects		Variance	Standard deviation
Observer (Intercept)		0.68	0.83	N/A

Final cumulative link mixed model estimates for each fixed, and random effect variable, as well as the result of testing for difference in observer ratings for simulation types and gender. For the simulations, the tests for difference in ratings were against real disfigurement samples. For gender, the test was against male target face samples.
