Duration of untreated psychosis as predictor of long-term outcome in schizophrenia: systematic review and meta-analysis

Duration of untreated psychosis (DUP) is one of the few potentially modifiable predictors of outcomes of schizophrenia. Long DUP as a predictor of poor short-term outcome has been addressed in previous meta-analyses, but the long-term effects of DUP remain unclear.

To analyse the associations between DUP and long-term outcomes of schizophrenia. METHOD: A systematic literature search was performed using seven electronic databases and manual searches. Random effects weighted meta-analysis with correlation coefficients was used to pool the results.
