Why Should I Contact Authors?
Sometimes, data is left out of published research. For this reason, it is a good idea to contact the author of the study to potentially acquire their datasets.
When reaching out to authors, use open-ended questions when asking authors for information regarding the study's design and its procedure (Cochrane Handbook, 2017). This is because asking direct questions "may lead to overly positive answers", which could introduce bias to the review.
