Abundance and diversity of Sphingomonas in Shenfu petroleum-wastewater irrigation zone, China.
Article in Environmental science and pollution research international, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
introductionMembers of the genus Sphingomonas have raised increasing attention due to their ability for polycyclic aromatic hydrocarbon (PAH) degradation and their ubiquity in the environment. However, few studies have revealed the ecological information on the abundance and diversity of Sphingomonas in the environment. MATERIALS AND
methodsA primer set targeting the Sphingomonas 16S rRNA gene was designed. The specificity was tested with four petroleum-contaminated soils by construction of clone libraries and further restriction fragment length polymorphism analysis. Subsequently, real time PCR and denaturing gradient gel electrophoresis (DGGE) assays were used to evaluate the abundance and diversity of Sphingomonas in the Shenfu irrigation zone, China.
resultsA genus-specific primer set SA/429f-933r was developed, and 90% of the sequences retrieved from soil clone libraries were related to Sphingomonas. Members of the genus Sphingomonas were detected in all soils, and significant correlation (p < 0.05) was observed between the Sphingomonas abundance and the ratios of PAHs to total petroleum hydrocarbon (TPH). DGGE profiles revealed Sphingomonas population structures differed greatly in different sites. The Sphingomonas diversity was not statistically (p > 0.05) correlated with the contamination level. Some of the soil-derived sequences were not grouped phylogenetically with sequences of known Sphingomonas, indicating new members of the Sphingomonas genus might be present in the Shenfu irrigation zone.
conclusionThe newly designed Sphingomonas-selective primers were specific and practicable for analyzing Sphingomonas abundance and diversity in petroleum-contaminated soils. The significant correlation between the abundance and the ratios of PAHs to TPH suggested an important role of Sphingomonas in PAH bioremediation.
