Part 2 -
Discuss now your report with your partner working through each item and the epidemiological principles. Complete the remainder of these questions. You may change your initial responses from the independent draft that was submitted prior to discussion.
With both reviewers discussing the ratings:
Is there a discrepancy between the two reviewers with respect to the component (A-F) ratings?
No Yes
If yes, indicate the reason for the discrepancy
1. Oversight
2. Differences in interpretation of criteria
3. Differences in interpretation of study
Describe what happened when you exchanged your drafts and the describe outcome of the discussion (you may describe what you learned during the process):
Final decision of both reviewers (circle one):
1. STRONG
2. MODERATE
3. WEAK
Results:
