Summary of Findings	Risk factors were an outcome a total of 965 times. These factors correlated weakly with global disease burden in disability-adjusted life years (r = 0.45) for all risk factors, but was high (r = 0.83) for metabolic risks, similar for behavioural risks (r = 0.46), and weak negative for occupational and environmental risks (r = 0.40).
