Core Tip

Core Tip: Iron deficiency is a common micronutrient deficiency with a worldwide impact. This bibliometric analysis was performed to analyze the literature on iron deficiency published between 2001-2020. Three international collaborative networks based in North America/India, Europe, and Asia were identified. There are 5 areas of greatest focus: Epidemiologic aspects of iron deficiency anemia, biochemical aspects of iron deficiency anemia, clinical evaluation of iron deficiency anemia, causes of iron deficiency anemia, and bioavailability of dietary iron. Evaluation of the papers published during this period identified epidemiology as the most cited area, and bioavailability of iron as the least cited.
