CspE is Overproduced by Temperature Downshift in the Acinetobacter johnsonii DBP-3.
Article in Current microbiology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 denitrifying bacterium Acinetobacter johnsonii strain DBP-3 which was capable of removing phosphate, nitrate, and ammoniacal salt is psychrotolerant, whereas, the cold shock response mechanisms or the cold shock proteins (Csps) was unclear. In this article, the optimal growth temperature (25 °C) and cold shock temperature (7.5 °C) were determined firstly by an Arrhenius plot of the growth of the strain DBP-3. Then, among the seven cold shock-like protein genes which were cloned and identified referenced by A. johnsonii SH046 genome, qRT-PCR and shotgun-LTQ mass spectrometry showed that Csp3 and Csp4 were overexpressed under cold shock condition. Furthermore, Western blotting confirmed the result with the antibodies against Csp3 and Csp4 prepared by ourselves. Finally, the phylogenetic analysis showed that the similarity percent between Csp3 and Csp4 was 76.85 %, and Csp3 and Csp4 belonged to CspE family. The results indicated that CspE is overproduced by temperature downshift and may play an important role in the psychrotolerant process of strain DBP-3.
