Overview

About

Maintained by Ralf HeroldCRAN page ↗GitHub ↗Website ↗Issues ↗

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' (https://www.isrctn.com/) and the 'European Union Clinical Trials Information System' ('CTIS', https://euclinicaltrials.eu/). Trial information is downloaded, converted and stored as JSON in a database ('PostgreSQL', 'SQLite', 'DuckDB', 'MongoDB' or 'MariaDB'; via package 'nodbi'). Protocols, statistical analysis plans, informed consent sheets and other documents in registers associated with trials can also be downloaded. Other functions implement trial analysis concepts canonically across registers, identify deduplicated records across registers, easily find and extract variables (fields) of interest even from complex nested data as used by registers, merge variables and update queries. The package can be used for monitoring, meta- and trend-analysis of the design and conduct as well as of the results of clinical trials across registers. See overview in Herold, R. (2025) doi:10.1017/rsm.2025.10061.

Changes in 1.26.3

Added support for MariaDB (nodbi v0.15.0)
Added tests to increase coverage of code testing
Type as NA new ISRCTN texts that indicate a value is missing
Added using all secondary ISRCTN identifiers for dbFindIdsUniqueTrials()
Refactored ctrFindActiveSubstanceSynonyms() to use MeSH terms in CTGOV2
Corrected f.primaryEndpointResults() for CTGOV (did not affect CTGOV2)
Corrected f.sampleSize(): for EUCTR, in news for 1.26.2 (#62), testing
Corrected import of history of results for EUCTR (euctrresultshistory = TRUE)
Minor update to browser script (see https://rfhb.github.io/ctrdata/#id_2-script-to-automatically-copy-users-query-from-web-browser)

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("ctrdata", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("rfhb/ctrdata")

Development version from rfhb/ctrdata. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-ctrdata

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-ctrdata

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-ctrdata

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
