PEDro is commonly used to assess which type of bias?

PEDro, which stands for the Physiotherapy Evidence Database, is primarily utilized to assess the methodological quality of randomized controlled trials (RCTs). The PEDro scale evaluates various aspects of research studies, such as randomization, blinding, and the presence of control groups, all of which are critical components in determining the reliability and validity of the trial's findings. By focusing on these methodological elements, PEDro helps researchers and practitioners identify the rigor and quality of the evidence presented in a study, allowing for better-informed clinical decisions.

Understanding methodological quality is essential because it directly impacts the interpretation of the results and their applicability to practice. Studies with higher methodological quality are generally more reliable, thus fostering confidence in their outcomes. This emphasis on methodological quality distinguishes PEDro from assessments related to external validity, participant consent ethics, or funding sources, which are not the primary focus of the PEDro scale.
