A reporting guideline specifies information that should be reported for a particular research type. It does not decide the question, comparison, sampling frame, causal claim or design validity.
Separate two decisions
- Choose the design from the question. Define the decision, population, unit of analysis, comparison, time structure and claim before selecting a method.
- Select the reporting guidance from the design. After the design is clear, use the appropriate guideline to identify the minimum information readers need.
- Use the checklist during planning. Reporting items can reveal missing protocol details before data collection, but they do not repair a weak design.
Why the distinction matters
EQUATOR defines a reporting guideline as a checklist, flow diagram or structured text developed to guide reporting of a specific type of research. Its purpose is transparency and completeness. A well-reported convenience sample remains a convenience sample; a complete checklist does not convert association into causation or make an invalid measure valid.
Worked use case
A researcher chooses a cross-sectional survey because STROBE exists for observational studies. The correct sequence is the reverse: first determine whether a cross-sectional design can support the intended claim; then use the relevant reporting guidance to document the design transparently.
Evidence boundary
Reporting guidance can improve transparency, replication and evidence synthesis, but compliance is not a quality score and does not establish that the research question, analysis or inference is appropriate.
