  1. Data ExtractionInteractive Quiz Prepared for: The Agency for Healthcare Research and Quality (AHRQ) Training Modules for Systematic Reviews Methods Guide www.ahrq.gov

  2. Evidence Tables: Design Evidence tables should be set at the beginning of a project and not changed, regardless of any unanticipated information or results found in the literature. • True • False

  3. Evidence Tables: Review Because of the typically large numbers of included studies, evidence tables need be reviewed only once for accuracy. • True • False

  4. Evidence Tables: Fields (I) The fields in an evidence table change from project to project. • True • False

  5. Evidence Tables: Fields (II) Which of the following could be possible fields for inclusion on an evidence table? • Country • Setting • Outcome • Study design • All of the above

  6. Evidence Tables: Discordant Information What should be done when two reviewers record different information in a certain evidence table field? • Calculate the average of the data recorded by both reviewers • Use the information that most closely conforms to the format of the table • Adjudicate by using a third reviewer • Exclude the study

  7. Summary • Evidence tables are an integral part of any review. • Proper table construction and thorough data abstraction are crucial for accurately conveying the results of a review. • Discrepancies in data between two reviewers should be adjudicated by a third reviewer.
