TL;DR: Several factors are found to be associated with psychotic disorders with different levels of evidence and represent a starting point for further etiopathological research and for the improvement of the prediction of psychosis.

TL;DR: The conceptual analysis showed that transdiagnostic research is grounded more on rediscoveries than on true innovations, and that it is affected by some conceptual biases, which can impact classification and clinical care.

TL;DR: This online individualized risk calculator can be of clinical usefulness for the transdiagnostic prediction of psychosis in secondary mental health care and may eventually facilitate the implementation of an individualized provision of preventive focused interventions and improve outcomes of first episode psychosis.

TL;DR: There is no evidence that any specific intervention is particularly effective over the others in preventing transition to psychosis, and sensitivity analyses controlling for different clustering of interventions did not materially affect the interpretation of the results.

TL;DR: A comprehensive and up-to-date synthesis of the evidence on the association between prenatal or perinatal risk and protective factors and psychotic disorders is provided and the robustness of these findings for most factors is confirmed.
