They play a key role in enhancing the validity, reliability, and transparency of scientific findings.
Example
At OMERACT, a methodologist collaborates with clinicians and patient research partners to develop and evaluate outcome measures for rheumatology studies. They ensure the survey instruments are valid, reliable, and feasible, and they guide the working group in applying appropriate statistical methods to analyze the data.
