Transition rates from schizotypal disorder to psychotic disorder for first-contact patients included in the OPUS trial. A randomized clinical trial of integrated treatment and standard treatment
Abstract
Background Only a few randomized clinical trials have tested the effect on transition rates of intervention programs for patients with sub-threshold psychosis-like symptoms.Aim To examine whether integrated treatment reduced transition to psychosis for first-contact patients diagnosed with schizotypal disorder.Methods Seventy-nine patients were randomized to integrated treatment or standard treatment. Survival analysis with multivariate Cox-regression was used to identify factors determinant for transition to psychotic disorder.Results In the multivariate model, male gender increased risk for transition to psychotic disorder (relative risk=4.47, (confidence interval 1.30-15.33)), while integrated treatment reduced the risk (relative risk=0.36 (confidence interval 0.16-0.85)). At two-year follow-up, the proportion diagnosed with a psychotic disorder was 25.0% for patients randomized to integrated treatment compared to 48.3% for patients randomized to standard treatment.Conclusion Integrated treatment postponed or inhibited onset of psychosis in significantly more cases than standard treatment.

The Stafford et al meta-analysis analyzed 11 studies, but one was open-label and another did not use standard clinical high risk for psychosis criteria, leaving nine studies with 1,043 patients in common with the current study.
“For example, the metaanalysis by Stafford et al 15 -on which current clinical guidelines are based -analyzed 11 studies, but one of them included an open-label trial (N5124) 94 and another did not assess participants against standard CHR-P criteria (N579) 20 , leaving nine studies (N51,043) that are in common with the current”

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.
