On multivariate analysis that included several demographic, laboratory, and metabolic factors, a trend toward significance was noted regarding the association between low phase angle on POD 10 and survival (Odds Ratio – 8.9, p = 0.09, Tab.
While multivariate analysis of factors associated with survival on POD 10 demonstrated only a marginally significant association for phase angle level on POD 10 (p = 0.09), we believe that this result is still meaningful and demonstrates that phase angle is a significant marker that reflects the metabolic status of the head and neck patient in the perioperative phase, enabling the multidisciplinary team to identify patients whose postoperative metabolic status requires further follow-up and support.
