The difference between studies with low risk of bias and those with at least some risk of bias was significant and we found considerable indications for researcher allegiance.

==Pseudoscience==
EMDR has been characterized as [[pseudoscience]], because the underlying theory and primary therapeutic mechanism are [[Falsifiability|unfalsifiable]] and non-scientific. EMDR's founder and other practitioners have used [[Pseudoscience#Falsifiability|untestable hypotheses]] to explain studies which show no effect.<ref name=ps-in_promotion>{{cite book |chapter=Chapter 4: Pseudoscience in Treating Adults Who Experienced Trauma |title=Science and Pseudoscience in Social Work Practice |vauthors=Thyer BA, Pignotti MG |year=2015 |publisher=Springer |page=221 |doi=10.1891/9780826177698.0004 |isbn=9780826177681|quote=Nevertheless, to date, given that there is no evidence that anything unique to EMDR is responsible for the positive outcomes in comparing it to no treatment and the florid manner in which it has been marketed, we are including it in this book... Another way in which EMDR qualifies as a pseudoscience is the manner in which it was developed and marketed... EMDR proponents have come up with ad hoc hypotheses to explain away unfavorable results that do not support its theory, which is one of the hallmark indicators of a pseudoscience... This type of post hoc explanation renders her theory unfalsifiable and thus places it outside the realm of science, because to qualify as scientific, a theory must be falsifiable.}}</ref> The results of the therapy are non-specific, especially if directed eye movements are irrelevant to the results. When these movements are removed, what remains is a broadly therapeutic interaction and deceptive marketing.<ref name="Herbert" /><ref name=Devilly2002>{{cite journal | vauthors = Devilly G |title=Eye movement desensitization and reprocessing: a chronology of its development and scientific standing |journal=The Scientific Review of Mental Health Practice |date=2002 |volume=1 |issue=2 |pages=132|url=http://devilly.org/Publications/EMDR-review.pdf}}</ref> According to neurologist [[Steven Novella]]:
