Number of biologic medicines relative to conventional medicines included in national essential medicines lists. Notes: The size of each circle represents the country’s health care expenditure per capita. The colour of each circle represents the country’s associated life expectancy. Greater life expectancy, health expenditure per capita, and number of conventional DMARDs listed are associated with a greater number of biologic DMARDs included. The association between the number of conventional DMARDs included and the number of biologic DMARDs included is visually evident in the World Health Organization (WHO) regions of Eastern Mediterranean, Europe, and The Americas
