Association between dietary niacin intake and suicidal ideation: mediating role of C-reactive protein.
Article in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundWhile dietary niacin intake is acknowledged for its beneficial impact on mental health, the precise relationship between dietary niacin intake and suicidal ideation (SI) remains unclear. This study seeks to explore the potential association between the prevalence of SI and dietary niacin intake.
methodsIn this study, the data of 26,224 American adults from NHANES were analyzed. To explore the association between dietary niacin intake and SI, as indicated by Item 9 of the Patient Health Questionnaire-9 (PHQ-9), restricted cubic spline, logistic regression, and stratified analyses were utilized. Furthermore, mediation analyses were performed to explore the role of C-reactive protein (CRP) in the association between SI and dietary niacin intake.
resultsAmong the subjects, 970 (3.7%) of them reported experiencing SI. Logistic regression analyses demonstrate a significant inverse association between dietary niacin intake and the prevalence of SI, even after adjusting for potential confounding variables (OR = 0.86, 95% CI: 0.77, 0.96). Subgroup analyses indicate a more pronounced association between SI and dietary niacin intake in individuals with a history of hyperlipidemia. Additionally, a non-linear association and saturation effect were observed between dietary niacin intake and the prevalence of SI, characterized by an L-shaped curve with an inflection point at 26.78 mg/day. Mediation analysis reveales that 3.6% of this association was mediated by CRP.
conclusionThis study indicates an increased dietary niacin intake associated with a reduced prevalence of SI, underscoring the potential public health and clinical importance of dietary niacin intake.
