Main Effect of Age-Group in Individual Facial Metrics.

Age groups			Mean diff.	SE	95% CI	F	${\eta }_{\text{p}}^2$
Cheekbone prominence						4.18**	.03
	20sa	30sa	.02*	.01	[.00, .04]
		40sa	.03**	.01	[.01, .05]
		50sb	.02*	.01	[.00, .04]
Face width to lower face height						8.93***	.07
	20sa	30sa	−.06***	.02	[−.09, −.03]
		40sa	−.07***	.02	[−.10, −.04]
		50s	−.06***	.02	[−.09, −.03]
Lower face height to full face height						26.40***	.17
	20sa	30sa	.05***	.01	[.04, .07]
		40sa	.06***	.01	[.04, .07]
		50sb	.05***	.01	[.04, .06]
fWHR						.72	.01
	20sa	30sa	.12	.14	[.15, .39]
		40sa	.16	.14	[−.12, .42]
		50sb	−.01	.14	[−.28, .27]

Note. SE = standard error; CI = confidence interval; ${\eta }_{\text{p}}^2$ = partial η²; fWHR = facial width to height ratio.
