Moreover, we found that: the United States of America led the most articles, Health Affairs, Value in Health, Journal of Health Economics, and Health Economics are the most important and relevant journals on this topic, and the most repetitive keywords after health insurance are coverage, services, reform, medical care, mortality, prevalence, and risk.
