Provides functions for querying, retrieving and analyzing
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 ('SQLite'
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.
