Description of the adapted criteria used to assess the methodological quality of the included studiesa
| Criteria | Description | |
|---|---|---|
| Study Sample | ||
| 1. | Recruitment | Sufficient details provided about the recruitment methods to allow replication |
| 2. | Participation rate | Participation rate of at least 80% among individuals who met eligibility criteria. This helps to demonstrate that the sample is representative of the target population. |
| 3. | Baseline characteristics | Description of baseline study sample provided. Must include the following key characteristics: age, gender, and smoking status |
| Follow-up and Attrition | ||
| 4. | Follow-up | Number of participants listed for each follow-up measurement (e.g., CONSORT diagram included) |
| 5. | Duration | Follow-up is a minimum of 2 months |
| 6. | Attrition | Response at final follow-up measurement was at least 75% |
| 7. | Non-response | Non-response is not selective at follow-up measurement(s) and attrition is the same across all study arms |
| Data Collection | ||
| 8. | Outcomes | Smoking related outcomes collected (either objective or subjective) |
| 9. | Objective measures | Objective clinical outcomes collected |
| Data Analyses | ||
| 10. | Statistical analyses | Appropriate statistical model was used |
| 11. | Statistical model | The number of cases was at least 10 times the number of independent variables |
| 12. | Interpretation | Presentation of confidence intervals, standard error, or effect size to assist with interpretation of clinically meaningful differences in outcomes |
