1 · What the graph read from it

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.

2 · The registry

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

Introduction: Early-course psychosis (ECP) exhibits marked heterogeneity in illness trajectories, with a substantial subset of individuals developing progressive symptomatic, cognitive, and functional decline. Although growing evidence implicates blood-brain barrier (BBB) and neurovascular unit (NVU) dysfunction in psychosis spectrum disorders, direct links between longitudinal clinical trajectories and disease-related cellular phenotypes remain insufficiently characterized. Methods and analysis: This protocol describes a standardized stem cell-based framework to model BBB and NVU dysfunction in ECP using induced pluripotent stem cells (iPSCs) derived from peripheral blood mononuclear cells (PBMCs) within a longitudinally characterized clinical cohort. The approach integrates donor-specific Ethics and dissemination: Ethical approval and informed consent for this study was obtained and the findings will be disseminated through publication in peer-reviewed journals and presentations at scientific conferences.
