New!

We are pleased to provide a test version of the RoB 2 tool for cluster-randomized trials.

Download the 18 March 2021* version:

• The full guidance document.

• The cribsheet summarizing the tool.

• A template for completing the assessment.

• An Excel tool to implement RoB 2 (contains macros; download to your computer before using).

*This version is the same as the 10 Nov 2020 version except for some re-ordering of questions in Domain 2 (effect of assignment to intervention) to make it consistent with the main version of RoB 2 for individually-randomized trials.
