Demonstration of cel operon expression of Escherichia coli, Salmonella typhimurium, and Pseudomonas aeruginosa at elevated temperatures refractory to their growth.
Article in Applied and environmental microbiology, 1992. 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
When Escherichia coli was incubated at the growth-refractory temperatures of 48 and 54 degrees C, expression of the cel operon was demonstrated by phospho-beta-glucosidase activity. This enzyme activity was also detected at the growth-refractory temperatures in Salmonella typhimurium and Pseudomonas aeruginosa. Thermotolerant and mesothermophilic mutants of E. coli, S. typhimurium, and P. aeruginosa, able to grow with generation times of 30 to 40 min at 48 and 54 degrees C, exhibited phospho-beta-glucosidase activity at their growth temperatures of 48 and 54 degrees C. Thus, the cel operon previously described as a cryptic operon in E. coli and S. typhimurium was found to be expressed at growth-refractory temperatures of the mesophilic parent and growth-permissive temperatures (48 and 54 degrees C) of the thermotolerant and mesothermophilic mutants.
