The participants had lower reported activity at study end, and even so this charlatan states publicly that music is an effective treatment for ME.
Looking at the abstract and table 2, the first part of your sentence seems to be both correct and relevant, but did W. really state that the treatment was effective?
Perhaps I missed something in the translation of the reply or was it in the paper (only skimmed)?
In the reply I only find
- the statement that his group was
"trying to improve the treatment options for patients with long-term fatigue" [not even ME/CF
S]
- as a conclusion derived from particular, ambitiuos arithmetics (applied to an intervention group with 15 and a a control group with 21 participants)
- "At follow-up after one year, the proportion of completely healthy young people, ie without fatigue, was about twice as high in the intervention group as in the control group. This may indicate that the treatment had positive long-term effects."
(However, I think he forgot to mention that the number of steps is still not only lower than pre-intervention but also lower than in the control group. Also, I think he forgot to mention that the reported fatigue and PEM scores decreased in both groups, indicating a reported improvement regarding symtoms of fatigue and PEM independent from group allocation, so that only the comparison between the groups, i.e the treatment effect, isn't significant with regard to the reported subjective symptoms.)
The abstract of the study paper only states that there were
"tendencies towards positive effects on patients’ symptoms and recovery" that
"might justify a full-scale clinical trial".
So all very vague, confusing, full of spin, but not a statement about an actual effect I think.
(The frequency of the words "tendency, "trend" and "not significant" in the trial paper seems to me...hm...to tend to be significant. Also, how did the investigators explain the correlation of a decrease in activity measured in step counts with improved PEM in the intervention group? Did the participants in the intervention group pace better to save their energy for the music sessions? Were they allowed to reduce school attendance? See
table 2 where more tendencies tend to be shown, e.g. it almost seems as if the intervention had a short term negative effect on the
control group...)
Edited for clarity.
