Neighborhood environments and transition to cognitive states: Sydney Memory and Ageing Study.

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
introductionFeatures of the neighborhood environment and ambient air pollution have been associated with onset and progression of neurocognitive disorders, but data from longitudinal population-based studies are limited.
methodsOne thousand thirty-six participants (78.3 ± 4.8 years) of the Sydney Memory and Ageing Study were followed for up to 13.7 years with biennial cognitive assessments. Neighborhood environmental features were assessed around the participants' homes. Associations between environmental features and transitions to cognitive states were estimated.
resultsPopulation density, street connectivity, access to commercial services, public transport, water bodies, and tree canopy were associated with a lower likelihood of worsening cognitive state. The opposite was observed for annual average concentrations of PM DISCUSSION: Healthy neighborhood environments may delay cognitive decline and the onset of dementia in older individuals. HIGHLIGHTS: This is the first published study on neighborhood built and natural environmental correlates of transition to dementia. This study was conducted in socially advantaged areas with relatively low ambient air pollution. Walkable neighborhoods are associated with a lower likelihood of worsening cognitive state. Neighborhood tree canopy is consistently predictive of better cognitive outcomes. Access to public transport, and blue and green spaces is associated with higher probability of improved cognitive state.
