Persistent Negative Symptoms: Characterization of an Unmet Need in a Learning Health System for First-Episode Psychosis.
Article in Schizophrenia bulletin, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
background and hypothesisPersistent negative symptoms (PNS) often emerge early in the course of schizophrenia spectrum disorders, significantly impair long-term functional outcomes, and remain difficult to treat, with no consistently effective interventions available. The manifestation of PNS in individuals with first-episode psychosis (FEP) engaged in coordinated specialty care (CSC) in the United States remains largely unknown. This study characterizes negative symptoms in routine clinical care using data from the Early Psychosis Intervention Network's Connection Learning Healthcare System, with a focus on a subcohort of individuals with PNS. STUDY
designPractice-based data were collected every 6 months over a 2-year period from 1289 participants across 23 CSC programs using a Core Assessment Battery (CAB) comprised of clinician-rated and self-report measures. Negative symptoms were quantified across CAB items, allowing for categorization of participants into PNS (n = 79) and non-PNS groups (n = 455). Group comparisons examined outcomes across CAB items, and exploratory mediation analyses focused on the role of engagement in outcomes relative to PNS. STUDY
resultsIndividuals with PNS had higher rates of schizophrenia and lower social and role functioning compared to those in the non-PNS group. Exploratory analyses indicated that service engagement at 6 months mediated the negative relationship between PNS and 12-month social and role functioning.
conclusionsThese findings highlight the challenge of PNS in individuals with FEP receiving CSC, the importance of early service engagement, and an opportunity to develop targeted interventions and refine treatment approaches to improve outcomes in this unique subgroup.
