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 as JSON in a database
        ('PostgreSQL', 'SQLite', 'DuckDB', 'MongoDB' or 'MariaDB'; 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 analysis concepts canonically across registers,
        identify deduplicated records across registers, easily find and
        extract variables (fields) of interest even from complex nested
        data as used by 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. See overview in
        Herold, R. (2025) <doi:10.1017/rsm.2025.10061>.
