Systematic reviews cannot be performed alone. One investigator is not sufficient to reduce the risk of bias in the review process.
It is essential that Cochrane reviews be undertaken by more than one person. This ensures that tasks such as selection of studies for eligibility and data extraction can be performed by at least two people independently, increasing the likelihood that errors are detected.
