also called clinical guidelines or clinical practice guidelines, recommendations to practitioners for addressing specific clinical situations, based on research evidence and opinions of experts

the original studies that are contained in a systematic review

the tendency of scientific journals to publish positive findings and reject negative findings

the statistic used to calculate effect sizes when the researchers know that study heterogeneity exists, meaning that the studies differ in terms of the treatments provided, the participants, or some other methodological factor

conducting a study that duplicates most or all the features of a previous study

an overview of the existing literature that typically does not answer a specific question and is not intended to provide a detailed synthesis of the literature. Often provides the basis for determining if a systematic review is possible.

research that combines the results of previously conducted studies, such as in a systematic review

condition that exists when studies within a systematic review differ on one or more important characteristics, such as interventions used, outcomes studied, or settings

a methodical synthesis of the research evidence regarding a single topic that can be replicated by others
