Especially for my pharmaceutical clients I often need to produce scientific presentation slides. I tend to take a different approach to the industry standard when I need to present to a non-scientific audience: split the chart in 2.
  1. Chart 1 focusses just on the message and is highly simplified (“Survival rates went up 35%”)
  2. Chart 2 provides all the details about the study (number of patients, patient profile, confidence interval)
Springing the full combined chart with all the detail will just overwhelm the laymen audience. Medical professionals have trained decades to extract chart 1 from the combined chart in a nano second. The average investor lacks this experience.
