1 · What the graph read from it

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.

2 · The registry

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

backgroundAlthough dietary omega fatty acids have been recognized for positive effects on mental health, the specific association between omega fatty acids intake and suicidal ideation remains ambiguous. This study aims to explore the potential association between the prevalence of suicidal ideation and dietary omega fatty acids intake in American adults.

methodsThe data of 27,944 American adults collected from National Health and Nutrition Examination Survey (NHANES) were analyzed in this study. To assess the association between dietary omega fatty acids intake and suicidal ideation as measured by Item 9 of PHQ-9, logistic regression, restricted cubic spline regression, and stratified analyses, mediation analyses were employed.

resultsLogistic regression analyses indicate that the intakes of omega-3 and omega-6 fatty acids were inversely associated with the prevalence of suicidal ideation, and dietary omega-6/omega-3 ratio was positively associated with the prevalence of suicidal ideation. Subgroup analyses further revealed a stronger association between suicidal ideation and omega fatty acids intake in individuals with a history of stroke. Furthermore, a saturation effect and non-linear association were identified between omega-3 and omega-6 fatty acids intake and the prevalence of suicidal ideation, characterized by an L-shaped curve with an inflection point at 1.36 g/d, 13.69 g/d, respectively. Notably, C-reactive protein (CRP) partially mediated the association between omega-6, omega-3 fatty acids intake and suicidal ideation by a proportion of 3.8% and 4.0%.

conclusionThe findings of this study suggest that higher omega-3 and omega-6 fatty acids intake and lower omega-6/omega-3 ratio is associated with a declined prevalence of suicidal ideation. CLINICAL TRIAL NUMBER: Not applicable.
