Pseudomonas seleniipraecipitans proteins potentially involved in selenite reduction.
Article in Current microbiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 29 papers.
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
Pseudomonas seleniipraecipitans grows in the presence of high levels of selenite and selenate and reduces both oxyanions to elemental selenium (Se(0)), a property that may make P. seleniipraecipitans useful as an inoculant for biobarriers designed to remove selenite or selenate from ground or surface waters. An earlier study showed that P. seleniipraecipitans nitrate reductase reduced selenate to Se(0), but failed to identify the protein(s) involved in selenite reduction. This study used ammonium sulfate precipitation, hydrophobic interaction chromatography, and native PAGE to isolate two electrophoretic gel regions, identified as bands A and B that showed selenite-reductase-activity. Proteomics was used to identify the proteins present in those regions. Glutathione reductase (GR) was detected in the A-band; based on this information, Saccharomyces cerevisiae GR, obtained from a commercial source, was evaluated and found to have selenite-reductase-activity, confirming that GR can reduce selenite to Se(0). Proteomics was also used to detect the proteins present in the B-band and thioredoxin reductase (ThxR) was detected as a B-band protein; based on this information, E. coli ThxR, obtained from a commercial source, was evaluated and found to have selenite-reductase-activity, confirming that ThxR can reduce selenite to elemental selenium. Thus, evidence presented in this study shows that S. cerevisiae GR and E. coli ThxR can reduce SeO3 (2-) to Se(0) and strongly suggests that P. seleniipraecipitans GR and ThxR can also reduce SeO3 (2-) to Se(0).
