Molecular evaluation on the distribution, diversity, and toxicity of Microcystis (Cyanobacteria) species from Lake Ulungur--a mesotrophic brackish desert lake in Xinjiang, China.

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
The distribution and diversity of the waterbloom-forming cyanobacteria, mainly including Microcystis species, were investigated using molecular approaches in Lake Ulungur, an increasingly eutrophic and brackish lake located in Xinjiang, China. Real-time PCR analyses showed the abundance of Microcystis 16S rDNA gene copies in the Ulungur Lake is low, at 7.2×10(4) copies L(-1) average and 4.5×10(5) copies L(-1) at maximum. Two Microcystis species, M. aeruginosa (Kützing) Lemmermann and Microcystis wesenbergii (Komárek) Komárek were, for the first time, reported in this lake. The mcyA gene-specific PCR determination on the isolates of Microcystis showed that the M. aeruginosa strains are all mcyA-containing genotypes, while M. wesenbergii are non-mcyA-containing ones. The microcystin contents of the toxic M. aeruginosa strains were shown to be lower than those of the Microcystis strains isolated from other eutrophic lakes in China. Phylogenetic analyses based on 16S rRNA and rpoC1 genes showed that the Microcystis strains isolated from the Ulungur Lake were not genetically divergent from those isolated in the other freshwaters. Such an investigation would contribute to the knowledge on the bloom-forming cyanobacteria of the increasingly eutrophic and saline lakes in the desert area.
