Examining sex as a potential moderator of metacognitive training for psychosis efficacy on cognitive insight and jumping to conclusions bias: Evidence from a large-scale harmonized database.

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: Whereas biological sex differences in psychosis are well-documented in terms of clinical presentation and illness course, their moderating role in the effectiveness of cognitive interventions remains unclear. Previous studies in first-episode psychosis (FEP) suggested sex-specific responses to Metacognitive Training for psychosis (MCT) on cognitive insight and jumping to conclusions (JTC) bias, but generalizability to broader clinical populations is unknown. Methods: This retrospective study analyzed harmonized individual participant data from 633 persons with schizophrenia spectrum disorders (SSD) who received MCT across 22 international studies. Treatment effects and potential sex moderation were analyzed using repeated-measures ANOVAs and mixed-effects logistic regression on cognitive insight (Beck Cognitive Insight Scale) and JTC bias (Cognitive Biases Questionnaire for Psychosis, JTC subscale; Beads tasks). Results: MCT produced significant improvements in cognitive insight and JTC bias, including reduced self-certainty ( Conclusions: Contrary to previous FEP-specific findings, sex does not moderate MCT efficacy in heterogeneous clinical samples including established schizophrenia. These results may support MCT implementation without sex-specific adaptations in routine clinical practice.
