Belief inflexibility reduces the impact of allostatic overload on psychotic-like experiences among Ukrainian refugees.

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
Introduction: Refugees are chronically exposed to cumulative stress, which may increase allostatic load (AL) and vulnerability to psychotic-like experiences (PLEs). Belief inflexibility, reflecting difficulties in revising beliefs in response to new information, may influence how physiological stress affects psychosis proneness. This study examined whether AL index interacts with cognitive biases and refugee status in predicting PLEs. Methods: Sixty Ukrainian refugees and fifty matched controls underwent psychiatric evaluation, assessment of cognitive biases, and measurement of AL biomarkers. Results: Refugees had fewer years of education and showed higher depressive, anxiety, PLEs, trauma-related symptoms, greater belief inflexibility and elevated AL index. Significant positive correlations were found between AL index and PLEs and between AL index and belief inflexibility. Moderation analyses revealed that both AL index and belief inflexibility were positively associated with PLEs, and refugee status amplified these effects. However, the interaction between AL index and belief inflexibility was negative, suggesting that higher cognitive rigidity weakened the direct impact of physiological stress on PLEs. Subsequent analyses indicated that this attenuating effect was especially pronounced in the refugee group. Discussion: These findings highlight the complex interplay between stress physiology andcognitive style in shaping psychosis vulnerability and adaptation in trauma exposed refugee populations.
