UbK is Involved in the Resistance of Bacillus Subtilis to Oxidative Stress.
Article in Current microbiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The objective of this study was to assess the role of UbK, a novel protein kinase, in the growth of Bacillus subtilis, especially under oxidative stress conditions. Growth profiles of wild-type and ΔubK mutant strains were assessed in the presence of paraquat, an in vivo inducer of oxidative stress. Wild-type B. subtilis cells were able to efficiently survive the stress conditions, whereas the growth profile of the ΔubK mutant strain was significantly affected. Complementation of the ΔubK mutant with a plasmid coding for a wild-type UbK restored wild-type growth phenotypes. Furthermore, we used recombinant plasmids containing the genes of the active kinase (UbK) and its inactive form (E106AUbK) to transform wild-type and ΔubK mutant strains. Our results showed that an active form of UbK is needed to restore a normal growth profile. Protein kinases allow a fine-tuning of cellular processes, including those related to metabolic adaptation to environmental cues. Our findings highlight the importance of an active UbK in the bacterial growth under oxidative stress in B. subtilis. This study revealed the role of a new protein kinase, UbK, allowing B. subtilis to survive oxidative stress.
