The natural way to express this data is as percentages of the population experiencing the event, or to establish the "risk" of an event occurring. These percentages may then be compared to assess the size of any difference between the groups. One way to do this is to look at the difference in the proportion in each group. This is a good way to get a handle on the size of the benefit. For statistical analysis, and especially meta-analysis, however it is more convenient to calculate the ratio of the two risks.
