In Reply Drs Platts-Mills and Jones have raised a potential concern with the search strategy used in our study on reanalyses of randomized clinical trial data, specifically with respect to our restriction to studies indexed as a clinical trial publication type in MEDLINE. We agree with them that a strategy with no restriction to clinical trials publication type would be more sensitive in detecting reanalyses.

However, performing such a search would yield a total of 112 330 citations (limited to March 9, 2014, as per our original search). Screening this number of citations would be a daunting task and may not be a valuable use of resources if the output of additional studies retrieved would be few in number compared with the studies retrieved in our original search.
