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 use of rubber has increased over the years, leading to a series of environmental problems due to its indefinite decomposition time. Bioremediation employing microorganisms have drawn an increasing interest and originated several studies of microbial rubber degradation. Genome sequencing and in silico analysis demonstrated that G. paraffinivorans MTZ041 isolate encodes the lcp gene (Latex Clearing Protein), responsible for expressing an enzyme that performs the first step in the assimilation of synthetic and natural rubber. Growth curves and scanning electron microscopy (SEM) were conducted for MTZ041 in natural (NR) and synthetic rubber (IR) as sole carbon source during 11 weeks. After 80 days, robust growth was observed and SEM analysis revealed the presence of bacilli and the formation of biofilm-like structures on natural and synthetic rubber. This is the first report of a G. paraffinivorans rubber degrader. Given the complexity of this substrate and the relative small number of microorganisms with this ability, the description and characterization of MTZ041 is of great importance on bioremediation processes of rubber products.
