A great stroke association would go through all the stroke research and test out whether that research is reliable enough to be used for stroke interventions. But that won't occur because we have NO stroke leadership and fucking failures of stroke associations. I don't see how any stroke medical professional can hold their head up with all the incompetency that they are letting slip by in stroke.
Oops, once again not following Dale Carnegie, 'How to Win Friends and Influence People'.

Low statistical power in biomedical science: a review of three human research domains
Abstract
Studies
with low statistical power increase the likelihood that a statistically
significant finding represents a false positive result. We conducted a
review of meta-analyses of studies investigating the association of
biological, environmental or cognitive parameters with neurological,
psychiatric and somatic diseases, excluding treatment studies, in order
to estimate the average statistical power across these domains. Taking
the effect size indicated by a meta-analysis as the best estimate of the
likely true effect size, and assuming a threshold for declaring
statistical significance of 5%, we found that approximately 50% of
studies have statistical power in the 0–10% or 11–20% range, well below
the minimum of 80% that is often considered conventional. Studies with
low statistical power appear to be common in the biomedical sciences, at
least in the specific subject areas captured by our search strategy.
However, we also observe evidence that this depends in part on research
methodology, with candidate gene studies showing very low average power
and studies using cognitive/behavioural measures showing high average
power. This warrants further investigation.
