An assessment of data and code availability in reviews

Transparency is vital for repeatability and verifiability of systematic reviews, as with all other research. Authors of quantitative systematic reviews (i.e. ones that include meta-analysis) can maximise transparency by publishing the data they collected and the analytic code describing and documenting their analyses. This project will conduct a map of evidence syntheses to assess the degree to which data and code used in meta-analyses are made public by authors and journals publishing systematic reviews in environmental science and healthcare.
