Characterizing the Clinical Trajectory and Predicting Persistence and Deterioration of Attenuated Psychotic Symptoms in Ultra-High-Risk Individuals.
Article in Schizophrenia bulletin, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAlmost 40% of individuals at ultra-high risk (UHR) for psychosis experience persistent attenuated psychotic symptoms (APS) yet it is unclear (1) whether they share overlapping clinical and functional outcomes compared to individuals who transition to psychosis, (2) when symptom and functioning trajectories begin to diverge between UHR individuals with different clinical outcomes, and (3) whether non-remission (persistent APS or transition) can be predicted using baseline and/or longitudinal data. STUDY
designParticipants were drawn from 2 randomized clinical trials: Neurapro (n = 220; discovery sample) and STEP (n = 180; external validation sample). First, 12-24 month symptoms and functioning were compared between UHR individuals with persistent APS, sustained remission, or transition to psychosis. Next, short-term changes in symptoms and functioning were compared between groups to determine timepoints at which trajectories began to diverge. Finally, we used support vector machines to predict non-remission (persistent APS or transition) vs sustained remission using data from baseline, 6-month follow-up, and combined baseline and 6-month follow-up.
resultsIndividuals with persistent APS had substantially poorer outcomes compared to those who remitted, and more closely resembled individuals who later transitioned to psychosis. Despite few baseline differences between groups, clinical and functional trajectories of the persistent APS and transition groups rapidly diverged from those who remitted. Prediction of non-remission was poor using baseline data but improved substantially when using 6-month follow-up or combined baseline-6-month data.
conclusionsUltra-high-risk individuals with persistent APS display similar clinical and functional trajectories to transitioned cases, suggesting that more intensive and sustained intervention is required for this subgroup. However, prospective identification of individuals with poor clinical outcomes (ie, persistence or deterioration of attenuated psychotic symptoms) may require longitudinal monitoring of symptom and functioning trajectories for several months.
