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

This pioneering study published in European Archives of Psychiatry and Clinical Neuroscience elucidates the mediating role of alexithymia-specifically difficulty identifying feelings (DIF) and externally oriented thinking (EOT)-in the pathway linking childhood trauma (CT) to negative symptoms (NS) in chronic schizophrenia (β < sub > DIF</sub > = 0.04, 95% CI [0.002, 0.085]; β < sub > EOT</sub > = 0.03, 95% CI [0.002, 0.060]). Using Hayes' PROCESS macro with bootstrapping in 94 patients, the authors establish alexithymia as a mechanistically actionable target for trauma-informed interventions. Methodological refinements are proposed to address antipsychotic class effects on emotion processing, neurobiological mediators (e.g., amygdala volume), and positive symptom confounding. This work redefines therapeutic paradigms for trauma-associated schizophrenia, underscoring the journal's leadership in transformative clinical neuroscience.
