  • Values are expressed as HRs.

  • *Previously married was defined as patients who have been married before but are living alone (after the death of the partner or divorce).

  • †Conditional mortality: excluding first 90 days after surgery.

  • ‡Disease-specific mortality: oesophageal or junctional cancer as the underlying or contributing cause. Model 1: unadjusted. Model 2: adjusted for sex, age, tumour stage. Model 3: adjusted for sex, age, tumour stage, histology, major complications, comorbidity and surgeon volume.
