dfFindUniqueEuctrRecord

A data frame created from the database that includes the columns
"_id" and "a2_eudract_number", for example created with function
dbGetFieldsIntoDf(c("_id", "a2_eudract_number")).

Code of single EU Member State for which records
should returned. If not available, a record for GB or lacking this, any
other record for the trial will be returned. For a list of codes of EU
 Member States, please see vector <code>countriesEUCTR</code>. Alternatively,
 "3RD" will lead to return a Third Country record of a trial, if available.

prefermemberstate

A logical value if trials should be retained
that are conducted exclusively in third countries, that is, outside
the European Union.

include3rdcountrytrials

The EUCTR provides one record per trial per EU Member State in which the
trial is conducted. For all trials conducted in more than one Member State,
this function returns only one record per trial.

internal

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.
