My new blog featured by @mad-in-america.bsky.social about what we can (need) to learn from fluoxetine trials for pediatric depression in order to judge other antidepressants commonly used for children and adolescents. A more elaborated version is on my website: ploederlm.github.io/blogs/fluoxe...

From Efficacy to Non-Efficacy: Lessons from Pediatric Fluoxetine Trials
Modern studies find that fluoxetine has lost its efficacy for children and can now be considered clinically equivalent to placebo.

This is very misleading. The effect size for treatment of .30 is a Cohen's d from RCTs, i.e. causal. The effect size for alliance is a Pearson's r of .30 (more like .6 expressed as d) and massively subject to confounding and reverse causation. So, this is not at all comparing like with like.

The average patient does not exist. I agree. Therefore, we cannot use average efficacy estimates from RCTs. Here it gets tricky, because this argument can be used to dismiss the poor average efficacy. Even more so no "super-responder" have been found yet. www.sciencedirect.com/science/arti...
