Describe the evaluation of the strength of the scientific evidence (i.e., Mill’s Canons).

•Brief introduction summary (design, sample, measure of exposure, measure of outcome, findings)•Discussion of the method to measure physical activity eg: what it appropriate for the study design and target population? Was it valid and reliable? What limitations or advantages?•Discussion of the dose-response relationship between physical activity (or sedentary behavior) and the health-related outcome (eg: CVD risk factors)•Evaluation of the strength of the scientific evidence (i.e., Mill’s Canons)•Discussion of the study’s strengths and weaknesses•Identification of future research needs •Conclusion/summary
