Comparison of the mean asymmetry indexes of the control and Treacher Collins Syndrome (TCS) groups in the skeletal and soft tissue models and bootstrap confidence intervals.

Group	Skeletal			Soft tissue
Group	Controls (n = 52)	Unoperated TCS (n = 14)	p-value	Controls (n = 52)	Unoperated TCS (n = 14)	p-value
Mean ± SEM	123.00 ± 4.89	197.80 ± 19.11	0.0018^a	87.59 ± 4.14	123.3 ± 9.697	0.0033^a
BCa 95% LCI	113.83	164.28	NA	79.09	107.3732	NA
BCa 95% UCI	131.55	232.55	NA	95.85	140.3852	NA

BCa: Bias-corrected and accelerated; LCI: Lower Confidence Interval ± (standard deviations) STD; Upper Confidence Interval ± STD.

Statistically significant (unpaired two-tailed t-test).
