Original research articles in JAMA are selected for publication because the results are valid and findings provide important new clinical, research, or policy-related insights. To be current, clinicians must read and understand the primary research literature. By implication, this means also understanding increasingly complex methodologies and statistical analyses now used in clinical research. Clinicians may not be familiar with research methods introduced after they completed training. Because relatively little emphasis is placed in medical school on research methods and statistics, clinicians may never have learned enough about these topics to properly understand current research articles.
