Cox regression of RFS for the 333 GIST patients.
| Factors | HR | 95%CI | P | |
|---|---|---|---|---|
| Time of drug | −0.936 | 0.906 | 0.967 | <0.001 |
| Size | 1.045 | 1.011 | 1.079 | 0.009 |
| Rupture | 2.811 | 1.740 | 4.541 | <0.001 |
| Site | 2.271 | 1.456 | 3.543 | <0.001 |

RFS – relapse-free survival; HR – hazard ratio; GI – gastrointestinal; CI – confidence intervals. A multivariate survival analysis was performed by the Cox hazards model and the confidence interval was 5–95%. P values <0.05 was considered statistical significance.
