Primary analysis (societal perspective): Cost-effectiveness planes indicating the uncertainty around the incremental cost-effectiveness ratios (Fig. 2 (1)) and cost-effectiveness acceptability curves indicating the probability of cost-effectiveness for different values ($) of willingness-to-pay per unit of effect gained from the societal perspective (Fig. 2 (2)) for QALY (a), pain intensity (b), disability (c), weight (d), and BMI (e) (based on the imputed dataset)
