Doesn't matter if the SD bars make it obvious. No layman can read such a chart. The text 110% makes it sound like the study PROVES without any doubt that the product had an effect.

"the lactate measurement shows a difference" "The lower lactate value with Powerinsole means longer performance and a later onset of muscle fatigue." and finally "Even with the first application of the power insole, a lower skin conductance is evident compared to the placebo. This means that the power insole can help reduce stress levels."

Nowhere are they talking about statistical significance.
