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!

Generally no. Say the incidence of brain cancer in the control group is 0.1%. A 98% increase means that the likelihood of brain cancer in the experimental group increased by 98% which would make it 0.198%
So if you had 10000 people in the control group and 10000 people in the experimental group, you would expect 10 people to develop brain cancer in the control group and 19.8 people to get brain cancer in the experimental group.
