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', ),
'ClinicalTrials.gov' ('CTGOV', using the classic interface at
, and 'CTGOV2', using the
current interface at ), the
'ISRCTN' ( ) and the
'European Union Clinical Trials Information System'
('CTIS', ).
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.
