NOTE: As of October 12, 2010, there is a problem with searches that return over 1,000,000 results. The format of the results returned from PubMed has changed slightly, and we have contacted NCBI to find out whether this is a temporary or permanent change. In the meantime, we are working on a temporary fix. If you are attempting a CANDID search and the literature score analysis appears to be stuck in a loop, please contact us using the Questions? Comments? tab.
