Table 1 Cost-effectiveness results

From: Invasive urodynamic testing prior to surgical treatment for stress urinary incontinence in women: cost-effectiveness and value of information analyses in the context of a mixed methods feasibility study

Investigation strategy Total avg. cost per woman (£) Incremental cost (£) Total avg. QALYs per woman Incremental QALYs ICER (£) Probability that IUT is cost-effective for different threshold values for society’s willingness to pay for a QALY
