Purpose:

This dashboard summarises the current evidence behind IMPALA’s impact. It maps each key claim to the evidence that supports it, including clinical outcomes, implementation findings, usability evidence, cost-effectiveness analysis, and remaining evidence gaps. It is designed to support transparent use of evidence in proposals, partner conversations, funder due diligence, and internal learning.

For a shorter summary of our evidence, please have a look at the following page:

How to use this page:

Each row represents one evidence claim linked to IMPALA’s theory of change. The table shows a short summary of the quantitative and qualitative evidence, the current evidence grade, and the main conclusion. To read the full synthesis behind a claim, open the relevant Claim ID.

Important notes:

• This is a living evidence repository and will be updated as new research is published and new implementation data becomes available.
• Not all claims are equally well-evidenced, and we have not selectively included only positive findings. Where evidence is limited, preliminary, unpublished, or still being generated, this is noted explicitly.

Evidence grading:

• Evidence strength reflects the maturity, consistency, and directness of evidence, not the importance of the claim.
• Evidence grading using the NSF-LTC framework is currently being implemented and will be added to this page in the future.
• Current grading uses the following definitions:
