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
Metal contamination is known to cause shifts in structure of freshwater assemblages where sensitive species do not survive and tolerant species thrive, and given their sensitivity, ubiquitous nature, and high abundances, microbes are ideal targets for biomonitoring assessments. However, the responses of diverse microbial communities to metal contamination in freshwater environments are currently understudied, particularly in the Southern hemisphere. Therefore, in this study we used environmental DNA metabarcoding to assess the influence of copper contamination events on an urban wetland. Laboratory-based microcosms with clean and contaminated sediments were spiked with copper sulphate to assess microbial responses. We saw significant microbial variation both over time and between concentrations, with responses varying between the microbes from uncontaminated and contaminated sediments; outlining how the dynamics develop over a concentration and temporal gradient and how they vary with assemblages from contaminated and uncontaminated environments, with seven families identified as possible indicators of metal contamination.
