F1ash, doesn't seem to me to be as an important a point as you are making it out to be. Sure the slide could have been a bit more informative. On the other side this was a presentation not a peer reviewed paper with graphs. I would expect what you are concerned with to be made explicit in a peer reviewed paper. On a presentation slide, I give them a bit more room.
After all if you look at that slide, the base line score was a 6. At the end of the chart the score was 8. That is a pretty respectable improvement for the group average over baseline. And it is above the control group average. Yeah, I'd like to see the individual data, the standard deviation, etc. Again it is not a peer reviewed paper.
That slide was part of a presentation and the audience had a minute or two to look at it and absorb the information while Missling was talking. When I watched the presentation I had the luxury of hitting the pause button to study the slides and absorb the information, in real time the audience did not. Even then, I watched the presentation twice to be able to keep up with everything Missling was saying in relation to what the slides were showing.
