Cost are rounded to nearest 10. QALYs are rounded to 3 decimal places QALYS; quality adjusted life year, LNG-IUS; levonorgestrel-releasing intrauterine system, ICER; incremental cost-effectiveness ratio.
*Deterministic sensitivity analysis 1 = Use median utility values.
#
Deterministic sensitivity analysis 2 = Use NICE assumptions.
°Deterministic sensitivity analysis 3 = Assigning EQ-5D completion date utility for change treatment, if change treatment date is the same as EQ-5D completion date.
