Standardized Betas from Hierarchal Multiple Regression Analyses Predicting Symptom Scores from Lymphedema Severity (n=79)

	VHNSS

Note:

⁽¹⁾

VHNSS= Vanderbilt Head and Neck Symptom Survey

⁽²⁾

“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.

⁽³⁾

“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.
