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

Background: Epidemiologic studies have associated higher neighborhood greenness with lower type 2 diabetes (T2D) risk. However, more work is needed to assess interrelationships between greenness, T2D risk factors, and T2D. Our aim was to prospectively evaluate the association between greenness and T2D incidence, and investigate effect modifiers, in the Nurses' Health Study (NHS) and Nurses' Health Study II (NHSII) cohorts of US women. Methods: Greenness exposure was defined using the normalized difference vegetation index (NDVI), a quantitative indicator of photosynthetic vegetation. We obtained 30m Results: During the 27 years of follow-up, there were 18,527 incident T2D cases. In fully adjusted models, the meta-analyzed hazard ratio was 0.96 (95% confidence interval = 0.95, 0.97) for a 0.1 unit increase in 2-year summer average NDVI. In NHS, stronger associations were found among participants in the lowest PM Conclusions: In one of the first US nationwide prospective analyses of greenness and T2D, we found a protective association robust to air pollution co-exposure adjustment and persistent across subpopulations.
