Informative abstracts provide more details than subtle descriptions, offering key arguments, research outcomes, study participants and other useful details from the research. Structured abstracts present information in separate sections for objectives, population, study method, results and conclusion, and are preferred in health science publications over unstructured abstracts which present information in a single paragraph. Descriptive abstracts describe the type of information found in the article without evaluating or offering conclusions, providing key terms and an outline of objectives, methods and scope.
