abstract: 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' (<http://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'). Documents in registers associated with trials
  can also be downloaded. Other functions 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
  meta-analysis and trend-analysis of the design and conduct as well as of the results
  of clinical trials.
