Short-term outcome data analyzing the impact of increasing duration of overlap as a continuous variable. Exact-matched patients with the most amount of overlap (top 10%) and least amount of overlap (bottom 40%) were also compared.
| 30-d Outcomes | Increasing Duration of Overlap | After Exact Match Not Limited by Surgeon | After Exact Match Limited by Surgeon |
| Readmission | P = 0.911.00 (0.99–1.01) | P > 0.991.00 (0.17–5.82) | P = 0.690.67 (0.08–4.48) |
| Reoperation | P = 0.911.00 (0.99–1.01) | P = 0.383.00 (0.32–78.99) | P = 0.691.50 (0.22–12.61) |
| Emergency department visits | P = 0.411.00 (0.99–1.01 | P = 0.630.50 (0.02–6.57) | P = 0.690.67 (0.08–4.48) |
| Mortality | P = 0.901.00 (0.94–1.05) | N/A | N/A |
| Morbidity | P = 0.701.00 (0.99–1.01) | P = 0.510.60 (0.12–2.60) | P = 0.510.60 (0.12–2.60) |
| Morbidity/surgical complication | P = 0.781.00 (0.99–1.01) | P = 0.390.57 (0.15–1.97) | P = 0.340.50 (0.10–2.01) |
