Abstract:
Study quality assessment plays a key role in every step of the process when conducting a systematic review. Checklists are used to perform an accurate quality assessment. They include generic questions relevant to the design of the studies included in the review. The checklist items can be modified in relation to the question-specific components related to participants, interventions and outcomes. Quality assessment is used to describe the selected studies, explain heterogeneity, decide on the feasibility of undertaking a meta-analysis, assess the strength of the collated evidence, and make recommendations for future research.
