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

Acidovorax sp. strain NA3 was isolated from polycyclic aromatic hydrocarbon (PAH)-contaminated soil that had been treated in a bioreactor and enriched with phenanthrene. The 16S rRNA gene of the isolate possessed 99.8 to 99.9% similarity to the dominant sequences recovered during a previous stable-isotope probing experiment with [U-(13)C]phenanthrene on the same soil (D. R. Singleton, S. N. Powell, R. Sangaiah, A. Gold, L. M. Ball, and M. D. Aitken, Appl. Environ. Microbiol. 71:1202-1209, 2005). The strain grew on phenanthrene as a sole carbon and energy source and could mineralize (14)C from a number of partially labeled PAHs, including naphthalene, phenanthrene, chrysene, benz[a]anthracene, and benzo[a]pyrene, but not pyrene or fluoranthene. Southern hybridizations of a genomic fosmid library with a fragment of the large subunit of the ring-hydroxylating dioxygenase gene from a naphthalene-degrading Pseudomonas strain detected the presence of PAH degradation genes subsequently determined to be highly similar in both nucleotide sequence and gene organization to an uncharacterized Alcaligenes faecalis gene cluster. The genes were localized to the chromosome of strain NA3. To test for gene induction by selected compounds, RNA was extracted from amended cultures and reverse transcribed, and cDNA associated with the enzymes involved in the first three steps of phenanthrene degradation was quantified by quantitative real-time PCR. Expression of each of the genes was induced most strongly by phenanthene and to a lesser extent by naphthalene, but other tested PAHs and PAH metabolites had negligible effects on gene transcript levels.
