Plasma Metabolomic and Proteomic Profiling of the Mechanisms Underlying the Cumulative Impact of Co-occurring Psychiatric Disorders on Atopic Dermatitis.

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
Atopic dermatitis (AD) has been linked to psychiatric disorders, but the cumulative contribution of psychiatric multimorbidity to incident AD remains unclear. We integrated genome-wide association study summary statistics with UK Biobank cohort, metabolomic and proteomic data to evaluate genetic relationships, longitudinal associations and putative biological intermediates. High-definition likelihood and bidirectional GSMR assessed shared genetic architecture and directionality. Cox models, multimorbidity counts, weighted composite scores and stratified analyses assessed incident AD, including effect modification by serum vitamin D. Plasma metabolomic and proteomic data were examined using mediation analysis and proteome-wide Mendelian randomization. Genetic liability to 5 psychiatric traits was associated with higher AD risk, whereas reverse AD-to-psychiatric effects were not supported. Psychiatric disorders were prospectively associated with incident AD, with higher risk among participants with co-occurring disorders and higher weighted psychiatric burden. Vitamin D status modified these associations although causality cannot be inferred. A branched-chain amino acid metabolic pattern showed statistically significant but modest mediation (1.04%). Proteomic analyses prioritized HLA-DRA, MMP12, TNFRSF14, and VCAM1 as nonspecific inflammatory proteins associated with AD risk in psychiatric populations. Psychiatric multimorbidity marks a sustained elevation in AD risk, potentially through overlapping inflammatory and metabolic pathways.
