A Novel Dietary Index for Gut Microbiota (DI-GM) is Associated With Inflammation, Mental Health, and Tumor Biomarkers in Adults: A Cross-Sectional Study.

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
The interplay between diet, gut microbiota, and mental health has garnered increasing attention. This study aimed to examine the association of a novel Dietary Index for Gut Microbiota (DI-GM) with depression, anxiety, and intestinal tumor biomarkers, and to explore whether gut microbiota composition mediates these associations. A cross-sectional study was conducted among 650 Chinese adults aged 18-65 years. DI-GM scores were calculated based on habitual dietary intake. Mental health was assessed using PHQ-9, STAI-A, PSQI, and WHO-5. Gut microbiota metrics (Firmicutes/Bacteroidetes [F/B] ratio, alpha diversity), inflammatory markers (CRP, calprotectin, TMAO), brain-derived neurotrophic factor (BDNF), and carcinoembryonic antigen (CEA) were measured. Linear regression and structural equation modeling were used to assess associations and mediation effects. Higher DI-GM scores were significantly associated with lower BMI, improved lipid profiles (↑ HDL-C:
