1 · What the graph read from it

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.

2 · The registry

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

Urban greenspace has been associated with improved cognition and reduced Alzheimer's disease (AD) and AD-related dementias (ADRD) risk, but findings remain mixed, study quality varies, and evidence is largely cross-sectional. To advance the field, we offer guidance to select and apply greenspace exposure measures in AD/ADRD research. Our interdisciplinary expert working group synthesized existing knowledge and developed consensus-based recommendations through collaborative discussion. In this paper, we outline hypothesized pathways, summarize data sources and measurement approaches, and propose criteria and recommendations to select and apply greenspace exposure measures in research. Based on hypothesized pathways, we recommend tree canopy cover for stress reduction, attention restoration, and improved mental health; parks for increased physical and social activity; and greenness for reduced harmful exposures, highlighting the Normalized Difference Vegetation Index as capturing multiple pathways. We also identify future research priorities to advance understanding of greenspace-AD/ADRD associations and support more rigorous, comparable, and policy-relevant evidence.
