Standardized Betas from Hierarchal Multiple Regression Analyses Predicting Cervical Range of Motion (CROM) Scores from Lymphedema Severity (n=80)

	Forward		Extension		Left Lateral		Right Lateral		Left Rotation		Right Rotation
	β	R2 change	β	R2 change	β	R2 change	β	R2 change	β	R2 change	β	R2 change
Final step: lymphedema severity		0.06		0.02		0.02		0.06		0.07*		0.08*
External (Foldi’s Stages)	−0.19		−0.14		−0.16		−0.25*		−0.28*		−0.27*
Internal (Patterson’s scale)	−0.13		0.06		0.02		0.09		0.07		−0.06
R2 (Full model)		0.15		0.07		0.11		0.17		0.26*		0.23*

Note:

⁽¹⁾“β” is the standardized coefficient that reflects the specific adjusted association of external and internal lymphedema with each of the measures after controlling for all covariates.

⁽²⁾“R² change” is the amount of variance accounted for by including both types of lymphedema severity after any covariates have been controlled for.

⁽³⁾“R² (Full model)” is the amount of variance accounted for by the whole model which includes covariates as well as lymphedema severity scores.
