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
objectivesTo estimate the prevalence of self-reported physician-diagnosed depression and to assess its association with self-perceived depressive symptoms, sociodemographic variables, physical activity, alcohol consumption, and smoking among Brazilian older adults.
methodsThis study employed a cross-sectional design using data from the Brazilian Longitudinal Study of Aging. The outcome was the self-reported physician-diagnosed depression. Independent variables included sociodemographic factors, physical activity, alcohol consumption, and smoking. The association between the outcome and self-perception of depressive symptoms was evaluated.
resultsData from 6,872 older adults were included. The prevalence of self-reported physician-diagnosed depression was 12.2% (95% confidence interval - 95%CI 11.4; 13.0). Self-perceived depressive symptoms were reported by 15.6% (95%CI 14.7; 16.5). Self-reported physician-diagnosed depression was higher among females (prevalence ratio - PR 2.23; 95%CI 1.80; 2.89), individuals with up to eight years of schooling (PR 1.32; 95% CI 1.10; 1.61), and those who did not engage in physical activity (PR 1.32; 95% CI 1.10; 1.57).
conclusionThe prevalence of self-reported physician-diagnosed depression among Brazilian older adults was 12.2%, independently associated with female sex, lower schooling, and physical inactivity. However, the prevalence of self-perceived depressive symptoms was even higher and was also associated with self-reported physician-diagnosed depression. Self-report may be a valuable tool, reinforcing the need for a hybrid approach that combines it with objective methods when addressing depression among older people.
