Table 2:

Multivariable logistic model for using opioids vs. not using opioids (n=87)

Characteristic	Odds Ratio (95% CI)	P-value
Age (years)	0.97 (0.94 – 0.999)	0.04^*
Male Gender (vs Female)	1.30 (0.37 – 4.62)	0.68
Charlson Score
1^st quartile (0 points)	Ref
2^nd quartile (1–2 points)	0.55 (0.18 – 1.74)	0.31
3^rd quartile (3–4 points)	0.82 (0.21 – 3.24)	0.78
4^th quartile (5–11 points)	1.99 (0.47 – 8.34)	0.35
Body Mass Index	0.93 (0.87 – 1.00)	0.06

Significant at p<0.05

Model p=0.05; Pseudo-R² = 0.11

Variables tested in the model but not included to limit variables or because not significant: Race-ethnicity, elapsed time between surgery and survey, type of surgery, length of admission, prior use of opioids.

Variables with p>0.25 in univariate analysis and therefore not tested in the model: central neck dissection, diagnosis of secondary hyperparathyroidism, history of chronic pain disorder, substance use, psychiatric illness or medication, prescription of a non-opioid analgesic, insurance status.
