Thanks as always for your input. But I'm confused with your vertical blue line and your statement that the blue line you added shows the delineation of greater benefit between the trial groups and the control groups.
For example I'm interpreting your statement to mean that on the left side of your blue line the trial group shows greater benefit and the on the right the control group is shows greater benefit and that the control group provided greater benefit for all categories except three.
However, when I read the chart I'm interpreting it as showing which group provides the better benefit by line where the pink shaded (control group dominant benefit) and the blue shaded (trial group dominant) areas meet. Therefore, I'm interpreting the chart to show that the trial group provides the greater benefit for all categories, not just 3, because the mean point for all data groups is in the blue shaded area.
Please correct me on how I'm misinterpreting what you said or how I'm reading the chart. Maybe there is some type of statistical qualifier that is implied in your statement that you assume most of us are aware of but in this particular case I'll admit that I'm not.
