confidence in the effect estimate, quality of the evidence, strength of the evidence
Certainty of the evidence is also referred to as quality of the evidence, confidence in the effect estimate, and strength of the evidence. It is an assessment of the likelihood that the effect will not be substantially different from what the research found; i.e. different enough that it might affect a decision.
Judgements about the certainty of the evidence are based on factors that reduce the certainty of the evidence (risk of bias, inconsistency, indirectness, imprecision, and reporting bias), and factors that increase the certainty of the evidence, such as dramatic treatment effects.
