Extremophile enzyme activity lab: using catalase from
Article in Journal of microbiology & biology education, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
There are places on earth that are considered to possess extreme physico-chemical characteristics as they relate to life. Surprisingly, there are microbes that have adapted various strategies that enable them to form robust communities in these environments. The microbes that live in these environments, called extremophiles, are described as being thermophilic, psychrophilic, halophilic, acidophilic, alkaliphilic, barophilic, and so on. Given that extremophiles were not discovered until relatively recently due to a view point that the environments in which they inhabited were not conducive to life, it is reasonable to conclude that the concept of extremophiles may be hard to grasp for students. Herein is described a laboratory exercise adapted from laboratory exercises that use mesophilic catalase enzymes to illustrate the influence of physico-chemical parameters on enzyme activity. Catalase is an enzyme that accelerates the degradation of hydrogen peroxide to water and oxygen gas. In addition to mesophilic catalases, the catalase from
