A meta-analysis of various tiny studies isn't going to predict the outcomes of only one large study.[14] Some have argued that a weak point of the strategy is usually that resources of bias usually are not managed by the method: a good meta-analysis can't correct for weak style and/or bias in the initial studies.[15] This is able to imply that only methodologically seem studies need to be included in a meta-analysis, a exercise termed 'ideal evidence synthesis'.

Other weaknesses are that it hasn't been decided Should the statistically most accurate technique for combining outcomes may be the fastened, IVhet, random or high-quality outcome products, nevertheless the criticism versus the random consequences product is mounting due to perception that the new random outcomes (Utilized in meta-analysis) are primarily formal gadgets to aid smoothing or shrinkage and prediction can be difficult or ill-encouraged.[26] The key dilemma Along with the random results dig this approach is usually that it utilizes the classic statistical considered producing a "compromise estimator" which makes the weights close to the The natural way weighted estimator if heterogeneity across studies is significant but close to the inverse variance weighted estimator if the involving study heterogeneity is tiny. On the other hand, what has become disregarded is the excellence among the product we choose to research a supplied dataset, as well as the system by which the information arrived into getting.
