Read the summary: A full description or abstract of the study's subject matter or intellectual content. The main goal of the summary is to give the user a clear sense of what the study is about, including the purpose of the study, the major topics covered, and what questions the principal investigators attempted to answer when they conducted the study. Note that summaries typically avoid attempting to address issues of how data might be used, who might be interested in the data, or any evaluative comments about the worth or usefulness of the study.
