Trial of Maintenance Therapy in Schizophrenia
Open accessAbstract
A double-blind, placebo-controlled trial was carried out to determine the value of maintenance therapy with phenothiazines in a population of outpatients who had recently recovered from an acute episode of schizophrenia. The drug was shown to be significantly more effective than the placebo in preventing relapse. The relationship of the trial patients to the population from which they were selected was defined in terms of clinical, historical, and social data. Maintenance therapy seems of little value in patients with a good prognosis and in the severely ill, but it is of value in the indeterminate group between these two extremes.

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.
