Furthermore, there is strong evidence that the average statistical power of a study ...

Isolated studies – Isolated studies are usually considered tentative and may change in the light of further academic research. If the isolated study is a primary source, it should generally not be used if there are secondary sources that cover the same content. The reliability of a single study depends on the field.
Indeed, a review of pharmaceutical studies revealed that research funded by drug companies was less likely to be published, but the drug-company-funded research that was published was more likely to report outcomes favorable to the sponsor. [5] A double-blind study with only objective measures is less likely to be biased to support a given ...
