The PRISMA flow diagram, depicting the flow of information through the different phases of a systematic review. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) is an evidence-based minimum set of items aimed at helping scientific authors to report a wide array of systematic reviews and meta-analyses, primarily used to assess the benefits and harms of a health care ...
The inclusion/exclusion model [ edit ] A more specific model to predict assimilation and contrast effects with differences in categorizing information is the inclusion/exclusion model developed 1992 by Norbert Schwarz and Herbert Bless.< [ 7 ] It explains the mechanism through which effects occur.

[1] It is sometimes referred to as the selection effect.
recommended by the Center for Science in the Public Interest (2003). Yet despite ongoing legislative debate, it is unclear whether these initiatives will have the intended effect, or, even if successful, represent the most effective means for producing such change. In order to address this question, we compared the efficacy of two different ...
A systematic review is a scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic. [1] A systematic review extracts and interprets data from published studies on the topic (in the scientific literature), then analyzes, describes, critically appraises and summarizes interpretations into a refined evidence-based ...
