BREAST-Q Dimensions	β	p	β	p	β	p	β	p
Satisfaction with breasts	3.11	0.32	2.23	0.56	2.29	0.58	9.57	0.03*
Physical well-being of the abdomen	−8.33	0.01*	−5.88	0.08	−2.77	0.53	−7.25	0.08
Physical well-being of the chest and upper body	−2.85	0.30	0.79	0.79	3.19	0.38	5.16	0.09
Satisfaction with outcome	2.13	0.53	4.01	0.32	−2.45	0.58	9.13	0.03*

^*Statistically significant (p < 0.05).

^†Each model included the following covariates: age at surgery, body mass index, timing of reconstruction (immediate v. delayed), flap type (muscle v. non-muscle), hypertension, Charlson Comorbidity Index, and history of pre-operative radiation.

^††The β coefficient refers to the predicted deviation in the dependent variable for each additional unit of independent variable.
