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
There is a gap in the literature regarding popular knowledge about dementia. Although dementia affects older individuals more frequently, it does not belong to senescence. Lack of awareness contributes to the normalization of cognitive decline, delaying the search for healthcare services, diagnosis, and treatments. Objective: Assess the population's knowledge about dementia and its relationship with socioeconomic characteristics. Methods: Cross-sectional study with a semi-structured questionnaire administered in person to a convenience sample of residents of Ribeirão Preto, São Paulo, Brazil. Descriptive and inferential statistical analyses were conducted. Significance level: p<0.05. Results: Three hundred residents were interviewed. Among them, 189 (63%) were unaware of the meaning of dementia. In a multivariable regression, higher income increased the odds of knowing what dementia is compared to the lowest income group (adjusted Odds Ratio [aOR]=4.29, 95% confidence interval [95%CI] 1.40-14.11, Conclusion: Significant lack of knowledge on the subject was observed, particularly among socioeconomic vulnerable individuals. Dementia was not widely recognized as a pathological and preventable condition. Given an aging society, this study provides a critical foundation for future public health initiatives and research aimed at improving dementia literacy and promoting early intervention.
