Search and filter all worksheets and research resourcesTOP transparency guidelines
Read the public TOP 2025 framework for registration, protocols, analysis plans, materials, code, data and reporting transparency. Adoption is not certification of a research claim.
ISRCTN public study records
Search freely accessible study-registration records and read registry guidance. Registering a new study normally incurs a fee, which may be covered by an eligible funder.
NC3Rs Experimental Design Assistant
Explore a free planning tool for animal experiments, including randomisation, blinding and sample-size support. Saving designs requires a free account; ethical approval remains separate.
Pandoc document conversion
Use free open-source software to convert research documents and format citations across supported file types. Inspect converted equations, tables and layout before sharing.
renv R project environments
Record and restore R package dependencies with free open-source software and documentation. Package lockfiles do not capture every operating-system dependency or data source.
OBO Foundry ontology registry
Find openly available biological and biomedical ontologies and principles for consistent identifiers, definitions and reuse. Check each ontology’s scope, version and attribution terms.
NCBO BioPortal ontology search
Browse public biomedical ontology terms, mappings and documentation when planning data coding. Individual terminology licenses and API access requirements must be checked separately.
ModernDive statistical inference textbook
Read the free online second edition covering R, visualization, regression, sampling and simulation-based inference. Print editions are separate; reuse follows the book’s license.
Audit Standardized Differences for Covariate Balance
Compare observed covariate distributions with an explicit standardization convention and a clear limit on causal interpretation.
Audit Collinearity with the Actual Regression Design Matrix
Investigate variance inflation without automatically deleting scientifically necessary variables.
Check Logistic Separation Before Trusting Large Coefficients
Recognize perfectly predicted outcomes and investigate unstable likelihood estimates before reporting odds ratios.
Make Regression Reference Categories Explicit
Audit factor levels and coefficient meanings so model tables and predictions describe the intended comparison.
