Discount factors were chosen on the relationship of the average time in the group of women after SpA (time from the reference SpA to the termination of subsequent pregnancy). There was no different in average time between the subgroups Treated, Untreated and Controls. The costs included the costs of screening for thyroid disease, regular endocrine controls, LT4 treatment and costs of pregnancy outcomes. Costs are calculated as a weighted average. Discount rate 3%, time horizon 4 years prospective, payer’s perspective. SpA, spontaneous abortion; SC, section cesarean.
