Environmental Adversity Is Associated With Attenuated Positive Symptoms and Complex Cognition in a Long-term Follow-up of the Philadelphia Neurodevelopmental Cohort.
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
backgroundEnvironmental adversity has been robustly associated with poor mental health outcomes, including psychosis spectrum (PS) symptoms and cognitive deficits. Environment may differentially impact males and females who differ in stress reactivity. We hypothesized that environmental adversity would predict later PS symptoms and neurocognitive deficits, and this relationship would be more pronounced in females. STUDY
designA sample of individuals (n = 343) from the racially diverse Philadelphia Neurodevelopmental Cohort, over-sampled for high and low adversity and psychosis risk at baseline (2009-2011), were assessed on average 11 years later. A baseline environment risk score (ERS) was calculated using established methods. The Structured Interview for Prodromal Syndromes assessed PS symptoms at follow-up, and the Penn Computerized Neurocognitive Battery assessed cognitive performance. Mixed-effects regressions were conducted for the full sample and stratified by sex assigned at birth. STUDY
resultsHigher baseline ERS was associated with greater PS symptoms (P = .006) at follow-up in the full sample. While there was no significant interaction of adversity × sex, after stratifying, ERS was predictive of total PS symptoms in females (P = .01). ERS impacted cognition in the full sample (P = .001) and in females (p = .003). Mixed-effects models did not reach significance for males. ANOVA results indicated that ERS impacted complex cognition specifically in the full sample (P = .001) and in females (P = .008) and trended toward significance in males (P = .049).
conclusionsFollowing early adversity, individuals are at risk for PS symptoms and cognitive deficits related to complex cognition.
