Reporting Guidelines Overview

Core summary

Reporting guidelines are structured checklists that ensure researchers report their studies completely and transparently. The EQUATOR Network is the central resource for finding the right guideline. Each study design has a dedicated guideline: CONSORT for RCTs, STROBE for observational studies, PRISMA for systematic reviews, and many more.

Detailed explanation

Poor reporting of research studies is a major contributor to research waste — if a study is not reported completely, readers cannot assess its validity, replicate it, or apply its findings. Reporting guidelines address this by providing minimum checklists of information that should be included. The major guidelines are: CONSORT (RCTs) — includes a flow diagram and 25-item checklist, STROBE (observational studies: cohort, case-control, cross-sectional), PRISMA (systematic reviews and meta-analyses) — includes the iconic flow diagram, STARD (diagnostic accuracy studies), CARE (case reports), COREQ (qualitative research), SQUIRE (quality improvement), TRIPOD (prediction models), SPIRIT (trial protocols), and ARRIVE (animal research). The EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network maintains a searchable database of over 400 reporting guidelines. Many journals now require submission of the appropriate reporting checklist. Using guidelines from the start — during study planning, not just at manuscript writing — improves both study conduct and reporting quality.

Clinical example

You write up your case-control study on risk factors for gestational diabetes. Before submitting, you download the STROBE checklist from EQUATOR and go through each item, ensuring your manuscript reports the study design, setting, participants, variables, data sources, bias, sample size, results, and limitations as recommended.

Research example

A 2014 study found that only 50% of RCTs adequately reported all CONSORT items. Journals that enforced CONSORT submission showed significantly better reporting quality — demonstrating that guidelines work when mandated.
