Systematic review | The Cochrane glossary [5] defines a systematic review as “A review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research, and to collect and analyse data from the studies that are included in the review. Statistical methods (meta-analysis) may or may not be used to analyse and summarise the results of the included studies.” |
Intervention review | Cochrane [6] defines an intervention review as follows: “Intervention reviews assess the benefits and harms of interventions used in healthcare and health policy.” |
Orthodontic interventions | Orthodontic interventions refer to the use of any type of orthodontic appliances that are used to move teeth or change the jaw size or position for orthodontic purposes. These interventions also include appliances to maintain or stabilize the results of orthodontic treatment, for example retainers. |
Adverse effect | Cochrane [4, 5] defines an adverse effect as “an adverse event for which the causal relation between the intervention and the event is at least a reasonable possibility.” |
