Cox Proportional Hazards Model for Overall Survival in Patients With Ovarian Cancer With Social Attachment Adjusted for Covariates
| Variable | HR | 95% CI | P |
|---|---|---|---|
| Age at cancer diagnosis | 1.04 | 1.01 to 1.06 | .002 |
| High grade v low grade | 2.06 | 0.44 to 9.65 | .360 |
| Advanced stage v early stage | 7.02 | 1.92 to 25.58 | .003 |
| Serous histology v nonserous | 0.70 | 0.33 to 1.50 | .840 |
| Suboptimal residual disease v optimal | 1.76 | 1.04 to 2.97 | .035 |
| Social attachment at cancer diagnosis* | 0.87 | 0.77 to 0.98 | .018 |

Social attachment score is used as a continuous variable; thus hazard ratio (HR) is expressed per one unit increase in social attachment score. In multivariate analyses, n = 166 because of two patients who could not be staged.
