Analytic Framework [PDF – 3.1 MB] – see Figure 1 on page 76
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 search for evidence started with seven computerized databases (MEDLINE, Sportdiscus, Psychlnfo, Transportation Research Information Services [TRIS], Enviroline, Sociological Abstracts, and Social SciSearch) and included reviews of reference lists and consultations with experts in the field. Studies were eligible for inclusion if they:
- Were published in English during 1980-2000
- Were conducted in an Established Market Economy*
- Assessed a behavioral intervention primarily focused on physical activity
- Were primary investigations of interventions selected for evaluation rather than, for example, guidelines or reviews
- Evaluated outcomes selected for review; and
- Compared outcomes among groups of persons exposed to the intervention with outcomes among groups of persons not exposed or less exposed to the intervention (whether the study design included a concurrent or before-and-after comparison)
* Established Market Economies as defined by the World Bank are Andorra, Australia, Austria, Belgium, Bermuda, Canada, Channel Islands, Denmark, Faeroe Islands, Finland, France, Germany, Gibraltar, Greece, Greenland, Holy See, Iceland, Ireland, Isle of Man, Italy, Japan, Liechtenstein, Luxembourg, Monaco, the Netherlands, New Zealand, Norway, Portugal, San Marino, Spain, St. Pierre and Miquelon, Sweden, Switzerland, the United Kingdom, and the United States.
The databases MEDLINE, Transportation Research Information Services (TRIS), Combined Health Information Database (CHID), ECONLIT, PsychInfo, Sociological Abstracts, Sociofile, Social SciSearch, and Enviroline were searched for the period 1980–2000. In addition, the references listed in all retrieved articles were reviewed and experts were consulted. Most of the included studies were either government reports or were published in journals. To be included in the review a study had to:
- Be a primary study rather than, for example, a guideline or review
- Take place in an Established Market Economy
- Be written in English
- Meet the team’s definitions of the recommended and strongly recommended interventions
- Use economic analytical methods such as cost analysis, cost-effectiveness analysis, cost-utility, or cost-benefit analysis; and
- Itemize program costs and costs of illness or injury averted
