- *Notes:
- For cohort studies: A. selection of the study groups (A1 indicates exposed cohort truly representative, non-exposed cohort drawn from the same community, A3 right method for ascertainment of exposure, A4 outcome of interest not present at start the representativeness of controls); B. cohorts comparable (B1 control of HIV risk factors except IPV, B2 control of any additional factor); C. outcome measurement (C1 quality of outcome assessment, C2, follow-up long enough for outcomes to occur, C3 complete accounting for cohorts).
- For case-control studies: A. selection of the study groups (A1 right case definition, A2 right controls definition, A3 the representativeness of the cases, A4 the representativeness of controls); B. comparability of the groups (B1 control of main confounders, B2 control of any additional factor); C. ascertainment of the exposure (C1 appropriate method of exposure ascertainment, C2 same method of exposure ascertainment for cases and controls, C3 same non-response rate of case and control groups).
- 1 indicates the study met the criteria; 0 indicates the study did not meet the criteria; A dash indicates fulfillment of the criteria could not be determined.
