Find_2, 'is the associated article cited or linked?' assesses if it is possible to trace data back to the original publication where the methods used to generate those data are described. 76% of primary data had a citation, however publisher-led copying of SI files to Figshare positively distorts this proportion, as the repository landing page provides this link back to the main manuscript. Find_3, 'is the dataset assigned a unique, citable and persistent identifier?' assesses if the data can be found over the long-term. We found poor compliance (24% of primary data) as only files uploaded to a formal repository had a DOI. Two datasets uploaded to Zenodo, 40 one data package deposited with an institutional repository, and MODEL data uploaded in native formats had a unique identifier assigned by the repository for the data or dataset. None of the SI PDFs containing MODEL data uploaded to Figshare can be considered to have a DOI specific to the primary data.
