Well, the range bands DO indicate universal symptomatic stabiliazation or improvement.

How you can interpret them differently, with no low range bars markdely below the mean data points reveals an ignorance of common statistical data presentation. Should anyone wish to continue to believe otherwise, he is welcome to that view. Those of us who have had elementary statistics know better.

In fact, that's exactly why range bars are included, to indicate the diversity of scores that were averaged to attain the mean (average) data points. With a long vertical range bar line, the reader knows scores were highly divergent, not centrally clustered, as they are with the Anavex2-73 cognition data.

If even one of the trial participants had typical symptomatic worsening during the course of the trial, each range bar would have gotten longer, descending ever farther beneath mean data plot, indicating that person's worsening condition. Didn't happen. Every participant had a favorable result (stabilization or symptomatic reduction).

There is no plainer way to present the plotted data. Just gotta know the rudiments of statistics.
