Threshold effect of visceral adiposity index on suicidal ideation: a mediation analysis through fasting blood glucose.
Article in Frontiers in psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Objective: The complex interplay between visceral adiposity and mental health outcomes, particularly suicidal ideation, remains a critical yet understudied area. Methods: This cross-sectional analysis utilized data from the National Health and Nutrition Examination Survey (NHANES 2005-2018), examining 11,931 adults aged ≥20 years. Visceral adiposity index (VAI) was calculated using sex-specific equations. Suicidal ideation was assessed using item 9 of the Patient Health Questionnaire-9 (PHQ-9). We employed multivariable logistic regression models, generalized additive models (GAM), threshold effect analysis using segmented regression, and mediation analysis via fasting blood glucose (FBG) with 5,000 bootstrap resamples. Results: A significant non-linear association between VAI and suicidal ideation was identified, with a threshold effect at VAI=6.81 (likelihood ratio test, P=0.006). Below this threshold, each unit increase in VAI was associated with 9.4% higher odds of suicidal ideation (OR=1.094, 95% CI: 1.028-1.163, P=0.005), while no significant association was observed above the threshold. FBG mediated 31.74% (95% CI: 4.43%-181.74%) of this relationship. The association was particularly pronounced among older adults (≥60 years), females, and individuals with diabetes or hypertension. Conclusions: These findings highlight the importance of considering visceral adiposity in mental health assessments, especially among vulnerable populations, and suggest potential metabolic pathways linking adiposity to mental health outcomes through glucose metabolism.
