Criteria | |
---|---|
Study participation | |

B. | Inclusion and exclusion criteria are adequately described. |
C. | There is adequate participation in the study by eligible individuals and sample size is sufficient. a |
D. | The baseline study sample (i.e., individuals entering the study) is adequately described for relevant key characteristics (at least for age and gender). |
Study attrition | |
E. | Response rate is adequate and there are no important differences between key characteristics and outcomes for participants who completed the study and those who did not (wave 1 and 2). a |
F. | Response rate is adequate and there are no important differences between key characteristics and outcomes for participants who completed the study and those who did not (wave 3 and follow-up). a |
Predictor measurement | |
G. | A clear definition or description of the predictor measured is provided. |
H. | Continuous variables are reported or appropriate (i.e., not data-dependent) cut-points are used. |
I. | The predictor measurement and method are adequately valid and reliable to limit misclassification bias. |
Outcome measurement | |
J. | A clear definition or description of alcohol use is provided. |
K. | Measuring and method of the outcome measurement is adequately valid and reliable to limit misclassification bias. |
Confounding measurement | |
L. | Confounders are accounted for in the study design (matching for key variables, stratification, or initial assembly of comparable groups) or in the analysis. |
Analysis | |
M. | There is sufficient presentation of data. |
N. | The strategy for model building (i.e., inclusion of variables) is appropriate and is based on a conceptual framework or model. |
O. | The selected model is adequate for the design of the study. |
P. | There is no selective reporting of results. |
