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
objectiveTo evaluate the association between major depressive episodes and diet quality among Brazilian adults and older adults.
methodsWe conducted a cross-sectional, population-based study using data from the two editions of the Brazilian National Health Survey (PNS in the Portuguese acronym) conducted in 2013 and 2019. Major depressive episodes were assessed using the Patient Health Questionnaire-9 (PHQ-9) and classified in two ways: based on a cutoff point of ≥ 9 points on the scale and according to the diagnostic criteria of the Statistical Manual of Mental Disorders. Diet quality was assessed using a diet quality score that considered the week consumption of seven food items. We used linear regression models to explore the association between major depressive episodes and diet quality score. Sensitivity analysis evaluating the association between major depressive episodes and each food item that composed the diet quality score was performed.
resultsIn both 2013 and 2019, individuals with major depressive episodes had a diet quality score 0.20 standard deviations higher compared to their peers, indicating a worse diet quality, regardless of the criteria used to define exposure and the potential confounders. Sensitivity analysis revealed a lower prevalence of regular consumption of beans, vegetables, fruits, and milk, and a higher prevalence of regular consumption of sugar-sweetened beverages and sweets among individuals with major depressive episodes.
conclusionMajor depressive episodes appear to be linked to lower diet quality in the Brazilian population. Policymakers and public health programs should consider approaches to improve both mental health and dietary habits.
