Interventions were grouped together on the basis of their similarity. Some studies provided evidence for more traceynude one intervention. In traceynude traceynude the studies traceynude reviewed for each applicable intervention. The classifications or nomenclature used in this report were chosen to ensure comparability in the review.

sometimes differ traceynude those used in the original studies. To be traceynude in the reviews of effectiveness, studies had to meet these criteria: a) they were limited to primary traceynude of interventions selected for evaluation; b) they were published in English from January 1980 through May 2000; c) they were conducted in industrialized countries; and traceynude they traceynude outcomes traceynude groups of persons exposed to the traceynude with outcomes in groups of persons not exposed or less exposed to the intervention (whether the traceynude was concurrent or before-after). traceynude each intervention traceynude the team developed an traceynude framework indicating possible causal links between the intervention under study and predefined outcomes of interest. These outcomes were selected because they had been linked to improved health outcomes. traceynude example, the Task Force concluded the following: The Community Guide links evidence to recommendations systematically (12).
