Therefore, in total 13/15 files were recovered and had PHI (87%). Since we were able to recover passwords using off-the-shelf tools, then it would be quite easy for an unsophisticated adversary to also do so.

Given the small number of trials from which we obtained files, broad generalization of the results is difficult. But we did expect that only trials that had good security and privacy practices would be willing to participate. We also expected that only study coordinators who were comfortable with the quality of their security practices would be willing to participate in the interviews. Therefore, the findings are expected to be biased toward those who were security-aware and were investing in protecting the data.
