There is an improvement but the improvement is not of significant difference above baseline apparently. The improvement may be due to the regular checkups that the placebo received as well.

Further analysis will show more. 26 weeks is short and the longer cohorts may show much better results. It's hard to say. I need to do more research. If the 52 week group shows significant improvement over their placebo counterparts that would be excellent results and can still occur afaik. I'd love to see what other holders say.

The results would look very nice if not for the recoveries of the placebo groups so you are right.
