Serious adverse events during follow-up
There were significantly fewer patients being readmitted to hospital
within 12 months of surgery and fewer patients experienced SAE(s) in the
low pressure group compared to the high pressure group (admissions:
9/44; 20% vs 15/44; 34%; incidence rate ratio IRR (low:high) = 0.31,
95%CI 0.15, 0.65, p=0.0008; one or more SAE: 9/48, 19% vs. 18/48,
38%;. OR = 0.39, 95%CI 0.15, 0.98, p=0.040), but the rate of
admissions and SAEs did not vary by harvest technique (admissions: IRR
(pedicled:conventional) = 0.84, 95%CI 0.44, 1.58, p=0.59; one or more
SAE: OR = 1.13, 95%CI (0.45, 2.82), p=0.79, Figure 3, Appendix
Tables A10 and A11 ).
