25% is super high to me but perhaps, you are right. But I would instead expect an invitation that state that editors in the series are not allowed publish any papers, unless, there is no other place for these papers. This would be more in line with COPE's opinions.

@floriannaudet.bsky.social the weird thing is, I have originally been hopeful that legitimate journals would use modern technology to improve the quality of the journals. They did not.

And I have been critical of some practices (like the uncritical use of the JIF), and eventually had to […]

Thanks for the support. 🙏

@floriannaudet.bsky.social @intconfchemstr that said, they could have written why they added that statement, but that only raises more questions, and highlights even more problems with the whole publishing system

So, are you right to reject the invitation? yes, I think that was a good decision […]

If there are alternative journals, COPE suggest that you should publish elsewhere. In my opinion, publishing where you are an editor should be an exception. Here it was an explicit invitation to self publish / and I can tell you that there were alternative journals given the topic.

I'm not sure about the very explicit incitation to self-publish. But this is a good point.

3/3 The so-called legitimate journals must resist the predatory practices of shitty journals. Not the opposite.

2/3 "You are also welcome to submit your own work. No more than 25% of articles in the Collection can be authored by the Guest Editor(s). The peer review and decision-making process of these articles will be overseen by a member of the Journal’s editorial board without conflicts of interest."

1/3 Today, I politely refused an invitation to serve as a guest editor on a topic that I like a lot in a journal that I also like (not a predatory venue). Why ? Because part of the invitation reads : ...

As Board Chair @floriannaudet.bsky.social put it: "Our first meeting showed the tremendous potential of this collaboration to deliver the rigorous, evidence-based guidance that Open Science policies need."
The first systematic reviews are coming.

Re-Analysis of three network meta-analyses of fluoxetine for depression in children and adolescents: clarifying efficacy and finding a zombie | RestoRes : Research integrity in biomedical research | O... Richard Lyus, Martin Plöderl and Florian Naudet will present how they discovered that a “zombie trial” can affect network meta-analyses and clinical guidelines on antidepressants for adolescents.

Tomorrow talk (hosted by University of Cambridge/CPFT Lunchtime Psychiatry Seminars) with R. Lyus and @ploederl.bsky.social will explore how a single “zombie” trial can meaningfully influence network meta-analyses and, in turn, shape clinical guidelines on antidepressant use in adolescents.

It was great to be part of the recent #datathon in Zeist/Utrecht. Three teams independently worked on Janssen's IPD (via YODA) to see if Esketamine has suicide preventive effects. All teams had to upload their protocol/SAP before accessing the data. The PhD students were amazing!

Very cool!

🙏 to all @sharectd.bsky.social crew including @ploederl.bsky.social. It was great to meet you there Martin, and, in addition, 🙏 for the chocolates, the family and I are more than happy.

I wish I could share more details now, but we need to consolidate the results and respect our data-sharing agreement. Still, there’s no doubt that in a few months, we’ll share a preprint, and soon after, a peer-reviewed paper, about this exciting exercise.

Yet, when multiple independent teams converge on similar interpretations, they can generate even stronger, more robust consensus.

Our experience underscores an important point: IPD meta-analyses are not “authoritative answers” to a research question, they are research objects, subject to analytical variability and researcher degrees of freedom.

✅ For the field of evidence-based medicine, this datathon is a rare example of multiple independent analysts exploring the same question on the same dataset, highlighting how research outcomes can vary depending on analytical choices.

✅ For clinicians and health authorities, particularly in contexts like the USA where “ketamine clinics” are increasing and everywhere since esketamine is gaining popularity. Our findings, positive or negative, will provide key insights for the field of suicide prevention.

The results of their 3 IPD meta-analyses are highly relevant...

Yesterday was the last day of our @sharectd.bsky.social Datathon 2 in Utrecth. Over the 1 week, 3 independent teams worked on the same research question: “Does esketamine have an impact on suicidality?”, using the same individual patient data shared by Johnson & Johnson on the The YODA repository.

Direction of effect and success of publcation: a randomized study has really been done already!

Well worth tuning in to!

Another talk on how a single small Zombie-trial biased the results for fluoxetine in influential Lancet meta-analyses. This time for the University of Cambridge.

Basic questions like "how many participants are in the dataset?" can produce surprisingly different answers between analysts.
