Abstract

The methods section of a scientific article often receives the most scrutiny from journal editors, peer reviewers, and skeptical readers because it allows them to judge the validity of the results. The methods section also facilitates critical interpretation of study activities, explains how the study avoided or corrected for bias, details how the data support the answer to the study question, justifies generalizing the findings to other populations, and facilitates comparison with past or future studies. In 2006, the Enhancing the QUAlity and Transparency Of health Research (EQUATOR) Programme began collecting and disseminating guidelines for reporting health research studies. In addition, guidelines for reporting public health investigations not classified as research have also been developed. However, regardless of the type of study or scientific report, the methods section should describe certain core elements: the study design; how participants were selected; the study setting; the period of interest; the variables and their definitions used for analysis; the procedures or instruments used to measure exposures, outcomes, and their association; and the analyses. Specific requirements for each study type should be consulted during the project planning phase and again when writing begins. We present requirements for reporting methods for public health activities, including outbreak investigations, public health surveillance programs, prevention and intervention program evaluations, research, surveys, systematic reviews, and meta-analyses.
