Childhood Trauma and Subjective Symptoms of Inflammatory Bowel Disease Health-Related Quality of Life in the General Population: The Mediating Roles of Emotional Suppression and Cognitive Control.
Article in International journal of environmental research and public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundInflammatory bowel disease (IBD) affects millions worldwide, imposing substantial clinical consequences and mental health implications. This burden leads to reduced quality of life (QoL) and growing pressure on healthcare systems and economies. This cross-sectional study examined the effects of childhood trauma on subjective symptoms of IBD health-related QoL, focusing on the mediating roles of emotional suppression and cognitive control, providing an integrative model for the general population.
methodsA sample of 402 Portuguese adults completed self-report measures, including the Childhood Trauma Questionnaire, the Emotion Regulation Questionnaire, the Cognitive Control and Flexibility Questionnaire, and the Short IBD Questionnaire. Multiple-step mediation analyses with bootstrapped confidence intervals tested indirect effects.
resultsThe two-step mediation effects indicated that childhood trauma was associated with subjective symptoms of IBD health-related QoL through both expressive suppression and cognitive control.
conclusionsThese findings highlight the pivotal role of developmental, emotional and cognitive factors in understanding IBD health-related QoL in the general population, offering an opportunity to capture undiagnosed, mild, atypical, or intermittent cases, often discarded from most clinical studies. General-population-based data collection on IBD, beyond clinical settings, is vital for informed resource allocation and the design of effective screening, prevention and public health interventions that capture both diagnosed and undiagnosed cases.
