Common Research and Publishing Abbreviations, Defined

This glossary provides a concise reference for the abbreviations most frequently encountered in clinical research, systematic reviewing, biostatistics and medical publishing. Each term is traced to the body that defines it.

Research and publishing abbreviations are used loosely across many disciplines, so that the same three or four letters may carry different meanings in different contexts. This glossary defines each term as the owning organisation defines it and groups the terms by the context in which they are most often encountered: trial conduct and data, publication ethics and reporting, and statistics and data tools.

Learning objectives

  • The expansion of each abbreviation in the terms used by its governing body.
  • The organisation or standard that defines each term, to permit independent verification.
  • The distinctions between related terms across the trial-conduct, publication-ethics and statistics-and-tools groupings.

Common misconceptions

  • “These abbreviations are interchangeable informal shorthand with no fixed meaning.” Most of the terms below are defined by a specific standard or governing body (ICH, ICMJE, COPE, AMWA, NLM), and loose usage can misstate a formal requirement, such as the required contents of a CRF or a SAP.
  • “"RCT" and "CRF" belong to the same category of term.” An RCT (randomized controlled trial) is a study design; a CRF (case report form) is a data-collection instrument used within a trial of any design. This distinction explains why the glossary groups terms by function rather than alphabetically.

Trial conduct and data

CRF — Case Report Form
A printed, optical or electronic document designed to record all the protocol-required information to be reported to the sponsor on each trial subject, as defined in ICH's Good Clinical Practice guideline1.
RCT — Randomized Controlled Trial
A study design in which participants are allocated to intervention groups by chance, so that comparison groups are, on average, equivalent except for the intervention under study; reporting of RCTs is standardised by the CONSORT statement2.
SAP — Statistical Analysis Plan
A document, finalised before unblinding, that sets out in technical detail how the principal features of a trial's design will be translated into a planned statistical analysis, per ICH E9 on statistical principles for clinical trials3.
PRO — Patient-Reported Outcome
Any report of the status of a patient's health condition that comes directly from the patient, without interpretation by a clinician or anyone else, as defined in the FDA's PRO guidance for industry4.

Publication, ethics and reporting

ICMJE — International Committee of Medical Journal Editors
A small working group of general medical journal editors that produces the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals, the reference most journals cite for authorship criteria and conflict-of-interest disclosure5.
COPE — Committee on Publication Ethics
A forum for editors and publishers to discuss research and publication integrity, which publishes flowcharts and guidance for handling suspected misconduct, redundant publication and authorship disputes6.
AMWA — American Medical Writers Association
A professional membership association for medical communicators that publishes a code of ethics for medical writers, including on ghost-writing and the disclosure of writing assistance7.
SME — Subject Matter Expert
A person with deep, specific knowledge of the clinical, scientific or regulatory area a manuscript or submission covers, typically consulted for technical accuracy rather than for writing or statistical work.

Statistics, literature search and data tools

MeSH — Medical Subject Headings
The U.S. National Library of Medicine's controlled, hierarchical vocabulary used to index articles in MEDLINE/PubMed, which is why a systematic search strategy is built around MeSH terms rather than free text alone8.
CINAHL — Cumulative Index to Nursing and Allied Health Literature
A bibliographic database covering nursing and allied-health journals, commonly searched alongside MEDLINE/PubMed and Embase in nursing and allied-health systematic reviews.
SAS and Stata
SAS (originally Statistical Analysis System, SAS Institute) and Stata (StataCorp) are commercial statistical software packages widely used for clinical-trial and epidemiological data analysis; both are named explicitly, rather than described generically, in most statistical analysis plans and methods sections.
SQL — Structured Query Language
The standard language for defining and querying data held in a relational database, used in clinical data management to extract and reconcile trial data.
STEM — Science, Technology, Engineering and Mathematics
An umbrella term for the science and technical disciplines, used in education and workforce policy rather than as a research-methods term.

Key points

Key points

Each of these abbreviations has a single correct, source-traceable definition, in most cases fixed by the standard or organisation that owns it (ICH, ICMJE, COPE, AMWA, the NLM). Authors are advised to link the first use of any abbreviation in a manuscript to that source rather than assume a shared informal meaning.

Practical application

Practical application

  1. Every abbreviation should be defined at first use. The term should be spelled out in full at its first appearance in a manuscript or protocol, with the abbreviation in parentheses, including terms that appear universally understood.
  2. Definitions should be cited from the owning standard, not from a general dictionary. Where precision is required, as with the contents of a CRF or the specifications of a SAP, the ICH or regulatory guidance that defines the term should be cited rather than a general glossary.
  3. Long documents should carry a running abbreviation list. A protocol or clinical study report with dozens of abbreviations should carry its own abbreviation table, matching ICH E3's expected structure.

Frequently asked questions

No; a CRF is the data-collection instrument (paper or electronic) used to capture protocol-required data from each subject, which is then entered into or generated as the trial database.

They overlap but differ in scope: ICMJE sets recommendations mainly for authorship, conflicts of interest and manuscript preparation across general medical journals, while COPE focuses on handling misconduct and ethics disputes across a broader range of publishers and disciplines.

MeSH indexing is specific to MEDLINE/PubMed, but a comprehensive systematic-review search strategy typically maps MeSH terms to the equivalent subject-heading or thesaurus terms used in other databases such as Embase or CINAHL.
