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/>),
'ClinicalTrials.gov' ('CTGOV', <https://clinicaltrials.gov/>) and
the 'ISRCTN' (<http://www.isrctn.com/>).
Trial information is downloaded, converted 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.
