Research Tools
Accessible tools for transparent and reproducible research
Think Denominator develops tools that remove avoidable technical friction while keeping important research decisions visible. Choose a browser-based reporting tool for a focused task, or an R package for a reproducible analytical workflow.

Public beta
Reporting Diagrams
Create publication-ready PRISMA 2020 and CONSORT 2025 flow diagrams. Counts remain in your browser, and arithmetic checks help identify inconsistencies without silently changing the data.
Open source
R Packages
Use documented R packages for epidemiological analysis and publication-ready output. Package availability, development status and citation information are maintained in the package catalogue.
Reporting Diagrams
PRISMA 2020
For new and updated systematic reviews using databases, registers and other identification methods.
CONSORT 2025
For parallel-group randomised trials with two to six groups, from enrolment to primary-outcome analysis.
Private by design. Diagram counts remain in your browser. Usage measurement records only content-free actions, such as opening a tool or downloading an output, so that Think Denominator can understand reach and improve usability.
Designed to Grow Carefully
Future tools may support additional reporting diagrams, study planning, data-quality review or practical learning. A new tool will be listed here only after its purpose, evidence base, privacy boundary, accessibility and export behaviour have been defined and tested.
This keeps the catalogue useful rather than filling it with speculative products or launch dates.
