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

introductionResidential greenspace is linked to mental and cardiometabolic health, but longitudinal studies on detailed greenspace and dementia incidence are limited.

methodsWe followed 2993 dementia-free participants in the Swedish National Study on Aging and Care Kungsholmen for 16 years; 477 developed clinically diagnosed dementia. Greenspace was assessed using normalized difference vegetation index within 100-, 250-, and 500-m residential buffers. Cox models estimated hazard ratios (HRs) per interquartile-range greenspace increment and tested effect modification by air pollution, road traffic noise, blue space, age, sex, and apolipoprotein E-ε4 (APOE-ε4).

resultsHigher greenspace within 100 m was associated with lower dementia incidence (HR = 0.79, 95% confidence interval [CI] = 0.64-0.96), whereas associations for larger buffers were attenuated. Associations were stronger in women (HR = 0.69, 95% CI = 0.54-0.89) than men (HR = 0.93, 95% CI = 0.71-1.24). DISCUSSION: Close residential greenspace may reduce dementia risk in older adults, particularly women.
