| IL-8 (pg/mL) | 0.043 | 0.27 | 0.786 | −0.050 | −0.22 | 0.823 |
| IL-10 (pg/mL) | 0.058 | 0.31 | 0.753 | -0.268 | −1.06 | 0.289 |
| TNF-α (pg/mL) | 0.069 | 0.30 | 0.763 | 0.030 | 0.11 | 0.916 |
Note: All models covaried for time, age, disease stage, surgical procedure, adjuvant therapy, and BMI. All predictors were standardized; therefore, coefficients represent the change in pain score for each 1 standard deviation increase in the predictors.
