i would say instead in your presentations that the graph shows that those w 4 or more ACE have 3x the likelihood of antidepressant RX in their lifetimes compared to those w 0 ACE...
because, no the graph does not mean "over 90% of people with an ACE score of 4 or more have been prescribed antidepressants at age 50 or at one point in the 50 years following their ACEs". the vertical scale on the graph is Rx rate per 100 person years. person years is not a concept general public typically encounters regularly.
Here's a definition of person years follows, see https://practice.sph.umich.edu...tral/person_time.php for examples
"A measurement combining the number of persons and their time contribution in a study. This measure is most often used as denominator in incidence rates. It is the sum of individual units of time that the persons in the study population have been exposed or at risk to the conditions of interest. The most frequently used person-time is person-years."
so would use the top statement instead which compares the rates (90 vs 30 Rx/100 person-years) of those w 4+ vs 0 ACE, ie 3 times more likely
