(Having said that, it looks like OP has done great work and this is a big red flag:)
I have attempted to make a comment on SMTM’s post linking to many of those studies, but they have not approved the comment. I have also attempted to contact them on Twitter (twice) and through email, but have not received a reply. All of this was over one week ago, and they have, since then, replied to other people on Twitter and approved other comments on their post, but haven’t commented on this. So I have no idea why their literature review excludes these studies.
This isn’t the core of why I think you think that’s a red flag, but for the record I don’t think a week is that much time to respond to public criticism. I have many important emails I don’t reply to for longer.
I was thinking about comment approval more than response [and to make that clearer, I appended to my quotation above]. I’ve been perma-declined myself, not fun. Unfortunately if it’s approved now there will be a question as to whether it was approved now in response to an ultra-popular LW post.

FWIW, the first time I contacted them about those studies was 15 days before the publication of this post.
