Subtype Comparison of Psychosocial Associations With Quality of Life in Functional Dyspepsia.
Article in Psychiatry investigation, 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
objectiveThis study aimed to examine the associations of childhood trauma, psychosocial resources (social support and resilience), and emotional distress with quality of life (QoL) in patients with functional dyspepsia (FD), and to explore potential differences between the epigastric pain syndrome (EPS) and postprandial distress syndrome (PDS) subtypes.
methodsThis cross-sectional study included 152 FD patients and 79 healthy controls who completed the Korean versions of the following instruments: Beck Depression Inventory-II (K-BDI-II), Beck Anxiety Inventory (K-BAI), Childhood Trauma Questionnaire (KCTQ), Multidimensional Scale of Perceived Social Support (MSPSS), Connor-Davidson Resilience Scale (CD-RISC-K), and World Health Organization Quality of Life Assessment Instrument Brief Form (WHOQOL-BREF). Negative affect was computed as a principal component analysis-derived composite from K-BDI-II emotional/cognitive items and K-BAI; QoL was a composite of WHOQOLBREF domains. Group differences were assessed using analysis of variance, and hierarchical regression analysis identified predictors of QoL within the patient group. Finally, multivariate regression models compared subtype-specific psychosocial associations.
resultsCompared to controls, patients with FD reported higher emotional distress and childhood trauma, lower psychosocial resources and QoL. Negative affect was consistently associated with lower QoL in both subtypes (EPS: β=-0.360; PDS: β=-0.300). Although direct statistical comparison of pathways between subtypes showed no significant differences, the most prominent protective factor within each group appeared to differ: in the EPS group, higher social support was the most significant predictor of better QoL (β=0.381, p=0.001), whereas in the PDS group, resilience was the key protective factor (β=0.360, p=0.001).
conclusionReducing emotional distress remains a central target for improving QoL in FD. Subtype-tailored emphases may be helpful- enhancing social support in EPS and bolstering resilience in PDS-while noting that between-subtype differences were limited and require confirmation in larger samples.
