  1. For each category low risk of bias is defined as: Study participation: The study sample represents the population of interest on key characteristics, Study Attrition: Loss to follow-up is not associated with key characteristics, Prognostics Factor Measurement: Factors are adequately measured, Outcomes Measurement: Outcome of interest is adequately measured, Study Confounding: Important potential confounders are appropriately accounted for, Statistical Analysis and Confounding: The statistical analysis is appropriate for the design of the study, Overall: Majority of criteria met. Little or no risk of bias.
