Analytic Framework [PDF - 2.43 MB] – see Figure 1 on page 32
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).

The following outlines the search strategy used for reviews of these interventions to increase use of child safety seats: Laws Mandating Use; Community-Wide Information and Enhanced Enforcement Campaigns; Distribution and Education Programs; Incentive and Education Programs; Education Programs When Used Alone.
The reviews of interventions to reduce motor vehicle-related injury reflect systematic searches of multiple databases as well as reviews of reference lists and consultations with experts in the field. The team searched six computerized databases (MEDLINE, Embase, Psychlit, Sociological Abstracts, EI Compendex, and Transportation Research Information Services [TRIS]), which yielded 10,958 titles and abstracts for articles, book chapters, reports, and published papers from the Association for the Advancement of Automotive Medicine proceedings about safety belts, alcohol-impaired driving or child passenger safety. Studies were eligible for inclusion if:
- They were published from the originating date of the database through June 2000 (March 1998 for child safety seat interventions)
- They involved primary studies, not guidelines or reviews
- They were published in English
- They were relevant to the interventions selected for review
- The evaluation included a comparison to an unexposed or less-exposed population
- The evaluation measured outcomes defined by the analytic framework for the intervention
The search strategy specific to child passenger safety is not available.
