1 Controlling
1.1 •randomisation
1.2 •restriction (use of inclusion/exclusion criteria)
1.3 •matching
1.4 •the analysis stage of research (i.e. stratification and modelling).
1.5 design of study methods before the data is collected
1.6 through analysis after the data has been collected
1.7 Study Designs
2 Systematic reviews
2.1 sum up the best available research on a specific question. This is done by synthesising the results of several studies.
2.2 uses transparent procedures to find, evaluate and synthesise the results of relevant research.
2.3 Procedures are explicitly defined in advance
2.3.1 in order to ensure that the exercise is transparent and can be replicated
2.4 also designed to minimise bias
2.4.1 relation to the articles selected for inclusion in the systematic review
2.4.1.1 Studies included in a review are screened for quality
2.4.1.1.1 the findings of a large number of studies can be combined
2.4.1.1.2 Peer reviewed
2.5 Criteria
2.5.1 •clear inclusion/ exclusion criteria
2.5.2 •an explicit search strategy
2.5.3 •systematic coding and analysis of included studies
2.5.4 •meta-analysis (where possible).
2.5.4.1 involves statistically combining the results of several separate studies to arrive at an overall result, which is often in the form of an 'effect size'.
