Interviewer: What symptoms did the study participants have? There is a whole range of symptoms that can be attributed to post-Covid or post-vaccine.

Schieffer: The question of symptoms is a very critical one. We selected the patients very carefully. We assigned the symptoms of our many patients to certain clusters using an AI-based mathematical algorithm. Based on this, we selected the patients and assigned them to this therapy.

Schieffer: The group we examined here had developed an infection-related lipid metabolism disorder; this is the largest group of patients.

I have a lot of reasons to be skeptical of this study based on this interview. Either way, cholesterol and blood-pressure lowering meds are cheap, safe, and widely available, literally any doctor can prescribe those for you right now.

Edit: Sorry, link does not open the table. It's table nr. 2.

I don't know where this claim of 90 % reduction in symptoms originated – the figures show an improvement of e.g. Bell 60 => Bell 80 for the Post Covid group, the other scales are similar. I'm not able to analyze all of the data at the moment, but at second glance this seems to be an effective treatment, changing the scores ~ 15–30 %. Far from 90 %. And the effect might be exclusive to Covid related problems.

Edit:

Bei bis zu 90 Prozent der Betroffenen milderten sich die Symptome wie Müdigkeit, Schwindel, Schlafstörungen oder Herzrasen ab oder verschwanden sogar ganz.

The responder rate was 90 %, not the reduction of symptoms.
