Description: A system for querying, retrieving and analyzing protocol-
        and results-related information on clinical trials from four
        public registers, the 'European Union Clinical Trials Register'
        ('EUCTR', <https://www.clinicaltrialsregister.eu/>),
        'ClinicalTrials.gov' (<https://clinicaltrials.gov/> and also
        translating queries the retired classic interface), the
        'ISRCTN' (<https://www.isrctn.com/>) and the 'European Union
        Clinical Trials Information System' ('CTIS',
        <https://euclinicaltrials.eu/>). Trial information is
        downloaded, converted and stored in a database ('PostgreSQL',
        'SQLite', 'DuckDB' or 'MongoDB'; via package 'nodbi').
        Protocols, statistical analysis plans, informed consent sheets
        and other documents in registers associated with trials can
        also be downloaded. Other functions implement trial concepts
        canonically across registers, identify deduplicated records,
        easily find and extract variables (fields) of interest even
        from complex nested data as used by the registers, merge
        variables and update queries. The package can be used for
        monitoring, meta- and trend-analysis of the design and conduct
        as well as of the results of clinical trials across registers.
