72 Chapter 2 Supplemental Table 2. Continued Biases Issues to consider for judging overall rating of “Risk of bias” 6. Statistical Analysis and Reporting Goal: To judge the risk of bias related to the statistical analysis and presentation of results. Presentation of analytical strategy There is sufficient presentation of data to assess the adequacy of the analysis. Model development strategy The strategy for model building (i.e., inclusion of variables in the statistical model) is appropriate and is based on a conceptual framework or model. The selected statistical model is adequate for the design of the study. Reporting of results There is no selective reporting of results. Statistical Analysis and Presentation Summary The statistical analysis is appropriate for the design of the study, limiting potential for presentation of invalid or spurious results.
