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

As sentinels of environmental changes, Antarctic lakes are ideal systems for studying the temporal and spatial dynamics of microbial communities. However, the relative magnitude and underlying mechanisms driving these variations remain poorly understood. Studying the spatiotemporal variation of microbial communities is crucial to provide a robust baseline for predicting ecosystem responses to global changes. Here, we investigated the spatial and inter-annual variation of bacterial community structure and their underlying assembly processes across sediment and water habitats in 11 lakes on the Fildes Peninsula, Maritime Antarctica, sampled during austral summers from 2017 to 2023, using 16S rRNA gene sequencing. The communities primarily clustered by habitat, with higher diversity in sediment (characterized by
