Rural-urban disparities in fruit and vegetable consumption and cognitive performance in Brazil.
Article in Revista brasileira de psiquiatria (Sao Paulo, Brazil : 1999). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesRural residents are exposed to many risk factors for poor diet quality, such as low socioeconomic status and food insecurity. However, the differences between urban and rural residents regarding the association of fruit and vegetable consumption with cognitive performance have not been explored. The aim of this study was to investigate the association of fruit and vegetable consumption with cognitive performance in urban and rural areas in a nationally representative sample of Brazilian older adults.
methodsThe sample included 9,412 adults aged 50 years or older from the Brazilian Longitudinal Study of Aging (Estudo Longitudinal da Saúde dos Idosos Brasileiros [ELSI]). The association between consumption of fruits and vegetables and cognitive performance was evaluated using linear regression.
resultsIn 8,158 participants (mean age 61.6 ± 9.3 years, 54% women, 44% White, and 15% from rural areas), the mean frequency of fruit and vegetable consumption was 2.0 ± 1.3 times a day. Higher intake of fruits and vegetables was associated with better memory (ß = 0.031, 95%CI 0.014-0.049), verbal fluency (ß = 0.030, 95%CI 0.004-0.056), and global cognition (ß = 0.035, 95%CI 0.015-0.055) performance in urban, but not rural residents (p for interaction = 0.036).
conclusionsHigher frequency of fruit and vegetable intake was associated with better cognitive performance in urban, but not in rural areas in Brazil.
