Trend analysis (one-way anova section)

hello, thanks a lot for the excellent tutorials. I was wondering if you could devote a subsection on the inspection of the trend that someone can observe from placebo-to-anxifree-to-joyzepam? I tried to look it up on the internet and there is little and confusing information about how to handle something like that. Thanks a lot and apologies if this "issue" is out of scope.
