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

The Urban Biotic Homogenization (UBH) hypothesis predicts that ecological communities should become increasingly similar in their species composition across an urbanization gradient, and that spatially independent cities should be more similar in species composition to each other than they are to their surrounding rural communities. However, there is conflicting scientific evidence for these predictions. Using 4 years of plant community data in 30+ urban community gardens across two European cities, we find no support for this hypothesis, especially among spontaneous, or wild plant species. Wild plant species exhibited increased biotic differentiation with urbanization (i.e., increased beta diversity), and plant species community composition was significantly different between the two cities. Wild plant species contributed more to overall beta diversity compared to cultivated plant species. These findings suggest that wild plant species may combat urban biotic homogenization in garden ecosystems and should therefore be supported to increase urban ecological heterogeneity.
