Survival outcomes of CRC patients following postoperative chemotherapy: multivariable Cox regression analysis
| Overall survival |
Disease-free survival |
|||
|---|---|---|---|---|
| HR (95% CI) | P value | HR (95% CI) | P value | |
| IBD vs non-IBD | 0.87 (0.53–1.4) | 0.58 | 0.57 (0.32–1.02) | 0.060 |
| Grade of differentiation (1 grade increase) | 1.3 (0.85–1.9) | 0.23 | 1.6 (1.02–2.5) | 0.041 |
Multivariable Cox regression was used to analyze overall survival, and competing risks analysis was used to analyze disease-free survival, censoring subjects who died from other causes or remained alive at end of follow-up.
