What does it mean if the experimental group in a study had an increased overall risk of brain cancer by 98%?

948 views

Let’s say there were 10,000 people in the study. If 100 people in the control got cancer, does that mean there were 98 more people that got cancer in the experimental group?

If anyone is interested in context, the study I’m referencing is linked [here.](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4602739/#!po=1.28205)

I want to make sure I’m interpreting these results correctly because this seems very high, thank you!

Yes, a 98% increase means almost twice as many subjects developed cancer. Depending on what the risk was to begin with though, twice as many can be one extra person on average or a hundred.
