File Sharing in Clinical Trials

1	Why are there few trials and files ? One question that has been brought up about our clinical trials file sharing study (see here: http://www.jmir.org/2011/1/e18/) was why there were few trials and files in the password recovery portion of the study. One of the challenges in doing this kind…
2	How come the 'hit rate' for the password recovery is so high ? In password cracking studies usually the success rate is lower than what we have reported here: http://www.jmir.org/2011/1/e18/. The reasons we think our hit rate was high are as follows: The passwords that we recovered were not unique for each file. Some…
3	Why didn't we use a more powerful password attack tool ? This question came up in the context of our study on clinical trials file sharin described here: http://www.jmir.org/2011/1/e18/ There are more "professional" grade password recovery tools that we could have used, such as jack-the-ripper. We chose the tools…
4	How generalizable are the conclusions from this study ? We have been asked about the generalizability of the clinical trials file sharing study here: http://www.jmir.org/2011/1/e18/ We must remember that this was a small study, although it did highlight some important issues. Below we will consider a number of…
