The majority of the evaluations employed the societal perspective. The time horizon of the evaluations ranged from 12 weeks to nine years. Most evaluations included less than 100 patients (n = 24), some even less than 50 (n = 16). We included five economic evaluations with a study population of n > 100 patients. The 30 evaluations bring the total number of patients in this review to n = 134,136.
