Univariate and Multivariate Regression Analyses of Predictors for Complete Response to the Treatment in Patients with Locally Advanced Nasopharynx Carcinoma
| Variable | Univariatea | Multivariateb | ||
|---|---|---|---|---|
| OR (95% CI) | P-Value | OR (95% CI) | P-Value | |
| Age | 1.1 (1.1–1.2) | 0.008 | 1.1 (1.1–1.3) | 0.005 |
| Gender | 2.6 (0.8–8.3) | 0.11 | ||
| Positive total CTC | 0.5 (0.1–1.4) | 0.17 | ||
| Triploidy CTC | 0.9 (0.7–1.1) | 0.31 | ||
| Tetraploidy CTC | 0.5(0.2–1.1) | 0.045 | ||
| Multiploidy CTC | 0.5(0.2–1.2) | 0.09 | ||
Notes: aUnivariate logistic regression analysis was used to investigate variables as potential predictors of complete response to the treatment. Variables included, age, gender, TNM stage, positivity of circulating tumor cells; bmultivariate analysis was performed using the backward method.
Abbreviations: CI, confidence interval; CTC, circulating tumor cells.
