Note:

⁽¹⁾FACT-H&N= Functional Assessment Cancer Therapy – Head & Neck

⁽²⁾PWB=Physical Well-being, SWB=Social/Family Well-being, EWB=Emotional Well-being, FWB=Functional Well-being, HNCS=Head & Neck Cancer Subscale, FACT-G=PWB+SWB+EWB+FWB, FACT-H&N Total=FACT-G and HNCS

⁽³⁾“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.

⁽⁴⁾“R² change” is the amount of variance accounted for by including both types of lymphedema severity after any covariates have been controlled for.

⁽⁵⁾“R² (Full model)” is the amount of variance accounted for by the whole model which includes covariates as well as lymphedema severity scores.

⁽⁶⁾* p<0.05, ** p<0.01
