This is ridiculous.

Your meta review has like 80%-90% of the studies on semaglutide and liraglutide. When finding random effect per drug, they even say this:

> Hence, the drugs eligible for meta-regression were semaglutide (subcutaneous injection, once weekly) and liraglutide (subcutaneous injection, once daily), which both showed a dose-dependent treatment effect in terms of weight and BMI.

And the class-effect is much more modest than semaglutide by itself would have shown, exactly as I said. What is the point?

Both meta-analyses above cover all eligible clinical trials for the respective strategies, targeting the GLP-1 receptor, or targeting amyloid.

For the GLP-1 strategy, Table 1 in the above paper shows that all drugs were clearly effective. Some were better than others.

For the amyloid strategy, only some of the drugs were effective, and that efficacy was very weak, even when all the drugs removed amyloid. This brings into question the hypothesis that removing amyloid would alleviate AD, i.e. the slender benefits of Lecanemab might not be caused by amyloid removal. The same cannot be said for the GLP-1 receptor agonists.
