| All-cause survival | HR 1.37 | 0.99–1.89 | 0.59–3.17 | Very low |
| Early postoperative mortality | OR 1.5 | 1.12–2.01 | 0.85–2.65 | Low |

| Postoperative complications | OR 1.1 | 0.96–1.25 | Not reported (k < 5) | Very low |
This research synthesises prognostic associations. It does not establish that improving social connection improves outcomes or predict individual risk. Confidence intervals for survival, readmission and complications include 1.

Show effect size and confidence separatelyPresent important outcomes, relative and absolute effects, available data and certainty, with reasons for downgrading.
GRADE evaluates a body of evidence for a particular outcome. Database inclusion or one study does not automatically establish high certainty.
These references support problem definition and evidence appraisal. Your conclusions still require project-specific sources and professional review.
