AnonymousPreliminary results from a study 'of' the impact of digital activity trackers on health risk status.

The digital activity trackers are the subject of the study.

Clarification: their impact on health risks is the topic or subject. If you read the study results you will expect to see something like this:

I see. What would be the difference if 'on' was used? Would it also be correct, as I have see
