Description: Provides functions for querying, retrieving and analysing
        protocol- and results-related information on clinical trials from
        two public registers, the European Union Clinical Trials Register
        (EUCTR, <https://www.clinicaltrialsregister.eu/>) and
        ClinicalTrials.gov (CTGOV, <https://clinicaltrials.gov/>). The
        trial information is transformed and stored in a database (RSQLite 
        or MongoDB, via nodbi). Functions are provided to identify de-
        duplicated records, to easily find and extract variables (fields)
        of interest even from complex nesting as used by the registers, 
        and to update previous queries that users retrieved in a database. 
        The package can be used for meta analysis and trend-analysis of
        the design and conduct as well as results of clinical trials.
