Fig. 2From: Is erenumab an efficient alternative for the prevention of episodic and chronic migraine in Spain? Results of a cost-effectiveness analysisWillingness-to-pay curve. The acceptability curve allows the identification of the likelihood of erenumab being cost-effective against topiramate (dark black dashes) and against placebo (grey dots) according to different willingness to pay. The probability of erenumab being cost-effective is above > 50% in the potential efficiency threshold ranges in Spain (30,000€ per QALY)Back to article page
