The benefit of treatments to prolong life can be described in two main ways: 1) how many months or years they add to an average patient’s life, or 2) how many patients benefit. Many times, a few people benefit a lot but most don’t benefit at all. This image tries to show how the average benefit relates to how many patients benefit.
This graphic uses a combination of bars and dots to represent the duality of what happens to patients who use the cancer drug. Note the use of outlining to group different labels with different visual elements.
This image scored higher on recall of average time saved, likely because this number is clearly placed in the middle of that graph. However, it does not clarify how rare it is for any benefit to occur. As a result, we do NOT recommend this graphic.
