Has speech and language therapy been shown not to work?
Open accessAbstract
In a recent trial investigating the effectiveness of speech and language therapy versus a control intervention in poststroke aphasia, patient outcome improved equally in both groups. However, flaws in the study relating to design of the control intervention, inadequate therapy 'dose', and the interpretation of null results should be highlighted.

In studies where both arms have an underpowered intervention (low dose), absence of a difference is the likeliest outcome.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
