Analytic Framework [PDF - 117 KB]
When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.
The number of studies and publications do not always correspond (e.g., a publication may include several studies or one study may be explained in several publications).

Electronic searches for literature were conducted in Medline, EconLit, and the database of the Office on Smoking and Health (OSH). The OSH database, a focused database of tobacco prevention and control articles, was so complete that we did not conduct searches of additional electronic databases. We also reviewed the references listed in all retrieved articles and consulted with experts on the chapter development team. With very few exceptions (e.g., one final report to the Robert Wood Johnson Foundation), included studies were published in journals. To be included in the review, a study had to
- Have a publication date of 1980 to May 2000
- Address at least one area in our conceptual framework (ETS, initiation, cessation)
- Be a primary study rather than, for example, a guideline or review
- Take place in an industrialized country or countries
- Be written in English
- Meet the evidence review and the Community Guide chapter development team’s definition of the interventions
- Provide information on one or more outcomes related to the analytic frameworks; and Compare a group of people who had been exposed to the intervention with a group of people who had not been exposed or who had been less exposed. (The comparisons could be concurrent or in the same group over a period of time.)
Our initial database searches were conducted in January 1998. A second database search was conducted in August 1999. Any study added after August 1999 was referred by members of the chapter development team or identified in the reference lists of retrieved articles.
