BSC = best supportive care; CE = cost-effectiveness; NA = not applicable; Ona A = onabotulinumtoxinA.

Note: Table 16 is based on both results from the manufacturer.

CADTH Common Drug Review (CDR) reanalyses could not provide an accurate estimate of the incremental cost-utility ratio (ICUR), given the issues around the model assumptions and uncertainties in the clinical data.
