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 potentially metabolically active components within the prokaryotic assemblages inhabiting the Antarctic Lake Limnopolar (Byers Peninsula, Maritime Antarctica) were investigated by a polyphasic approach which included culture-dependent and culture-independent methods (based on RNA molecules). Results support previous observations on the Proteobacteria and Bacteroidetes dominance, followed by Actinobacteria, in Antarctic lakes. In particular, Alpha-, Betaproteobacteria and Bacteroidetes were mainly detected by CARD-FISH and cDNA cloning, whereas Gammaproteobacteria and Actinobacteria dominated within the cultivable fraction. Overall, this study demonstrates the survival potential and physiological heterogeneity of the prokaryotic community in the Lake Limnopolar. The microbial community composition in the lake is affected by external influences (such as marine environment by sea spray and seabird dropping, and microbial mats and mosses of the catchment). However, most external bacteria would be inactive, whereas typical polar taxa dominate the potentially active fraction and are subsidized by external nutrient sources, thus assuming the main biogeochemical roles within the lake.
