As being a hypothesized mechanisms for developing the info, the random effect model for meta-analysis is foolish and it is more ideal to consider this model as a superficial description and one thing we choose being an analytical Software – but this option for article meta-analysis may well not work because the study consequences are a fixed element of your respective meta-analysis and also the probability distribution is only a descriptive tool.[27] Troubles arising from agenda-driven bias[edit]
