Note: AU$ = Australian dollar; INB = incremental net benefit; EVPI = expected value of perfect information; EVPPI = expected value of perfect parameter information; EVSI = expected value of sample information; ENBS = expected net benefit of sampling; NPWT = negative pressure wound therapy; CS = caesarean section; PU = pressure ulcer; Comp. Time = approximate computation time.
a.
For the parameter with the highest value (i.e., relative risk).
b.
For a sample size of 220 patients in the tissue adhesive, 200 patients in the NPWT, and 1200 patients in the nutritional support.
