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.
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 continental subsurface hosts energy-constrained groundwaters with a high diversity of ecologically elusive microorganisms adapted to the prevailing low-energy conditions. This study explored potential interactions among microbes using anaerobic enrichment incubations with three types of groundwater of contrasting hydrochemistry from the Äspö Hard Rock Laboratory, Sweden. Removing cells larger than 0.45 µm from the inoculum resulted in incubations enriched in populations characterized by very small genomes, including Patescibacteria, Nanobdellota, and Omnitrophota. These incubations had a higher diversity than non-fractionated incubations. However, cell numbers and community structure of the fractionated incubations did not change over an incubation period up to four months, despite high microbial diversity and experimental amendments with either simple (acetate) or more complex (cell lysate) carbon sources. In addition, network analysis on the groundwaters revealed multiple co-occurrences between populations affiliated with the Patescibacteria and the Desulfobacterota. Overall, these findings support that a considerable part of microbial diversity has a small cell size in these low energy groundwaters and strong co-occurrences among populations as an important survival strategy.
