Table 2. Logistic regression of the ORs (95% CI) for fatigue and associated factors.

Fatigue is divided into fatigue (FSS ≥4) and non-fatigued (FSS <4) groups.

OR, odds ratio; CI, confidence interval; FSS, fatigue severity scale.

^*Covariates with P-values less than 0.05 in univariate analysis and clinically significant variables including sex, age, body mass index, systolic blood pressure, diastolic blood pressure, pathology, stage, surgery, chemotherapy, radiotherapy, family history of cancer, smoking, exercise, alcohol, anemia, and subjective symptoms were included in the multivariate analysis. Other variables, not shown in this table, were removed using optimized multivariate regression analysis.
