methodological quality


Also found in: Dictionary, Thesaurus, Encyclopedia.

methodological quality

The extent to which the design and conduct of a trial are likely to have prevented systematic errors (bias). Variation in quality can explain variation on the results of trials included in a systematic review. Rigourously designed (better quality) trials are more likely to yield results that are closer to the “truth” (i.e., unbiased).
