Biography
Dr. Bradley Johnston is an Associate Professor in the Departments of Nutrition (primary appointment), Epidemiology and Biostatistics at Texas A&M University. Dr. Johnston obtained his PhD in Experimental Medicine from University of Alberta, and he completed post-doctoral training at Oxford University in Evidence-Based Health Care, and McMaster University in Clinical Epidemiology and Biostatistics.
Dr. Johnston’s work involves health status measurement (e.g. health-related quality of life, minimal important difference), and the application of randomized trial, systematic review, meta-analysis and clinical and public health guideline recommendation methods to a wide range of areas, with a particular interest in Evidence-Based Nutrition.
As the Director and Co-founder of EvidenceBasedNutrition.org, Bradley leads an international consortium of academics developing educational materials (e.g. workshops, guidance papers) to support evidence-based nutrition practice, as well as an international consortium of researchers and research trainees developing high quality, value-added systematic reviews and guideline recommendations on major clinical and public health nutrition questions.

Abstract
Estimates of Effect for Diet & Lifestyle Interventions: Minimal Important Difference and Certainty of Evidence
Estimates of Effect for Diet & Lifestyle Interventions: Minimal Important Difference and Certainty of Evidence
The presentation will highlight key steps for interpreting study results. Using data from Mediterranean-style dietary interventions, we will explore the variety of outcome data that exists, relative versus absolute estimates of effect, minimal important difference estimates, and the certainty of evidence for the estimated effects based on GRADE and alternative methods.
