Why We Still Need HBV Population-Based Epidemiologic Studies

As a practicing physician, i face clinical problems every day. to solve them, i use clinical decision making skills including reaching the most accurate diagnosis and deciding on the next step or steps to manage the problem. a clinician is a pragmatic person; i.e., s/he needs practical, implementable data to guide reasoning or decision making and nothing else! in this environment, why is mohammad reza ghadir’s article on the epidemiology of hepatitis b virus infection in this issue of the journal at all? (1). of course it is a socratic question, and you may find me to be the author of similar articles (2).
