Incremental cost-effectiveness ratio (ICER) tornado diagram for one-way sensitivity analyses at 3-month assessment with inpatient costs calculated for the observed admission time. The minimum and maximum values for each input variable are presented in brackets and the dashed line represents the willingness-to-pay threshold. a Sensitivity analyses with QALYs change computed based on the area under curve approach; b Sensitivity analyses with QALYs change computed based on the change from baseline approach
