*Patients who died within one calendar year (n = 97) were not included in analysis for factors associated with stoma non-reversal
**The most deprived SIMD quintile is SIMD 1, which is the most deprived 20% of the Scottish population based on address and postcode
***Calculated total from the 248 older adult patients (48.2%) who had a formal frailty score documented
