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 organization of bacteria has a central role in shaping interactions, dynamics, and composition within communities and microbiomes. Bacteria form distinct spatial patterns that have often been attributed to microbial processes such as chemotaxis, nutrient transport, and signaling. However, common patterns are observed across distinct bacteria and conditions, suggesting that a general organizing principle could direct bacterial organization. Here, we find that the organization of bacteria is explained by geometric ordering that promotes space-filling efficiency, giving rise to geometric patterns known as Voronoi tessellations. We find that the Voronoi Growth Model accurately predicts bacterial pattern formation in diverse conditions including in biofilms at the liquid-air interface, swimming populations, the zebrafish gut, and conditions that promote swarming. The patterns are observed in two and three dimensions, at the cm and mm length scales, across diverse species (
