1 · What the graph read from it

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.

2 · The registry

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

Practical lab exercises that help students draw connections between genotype and phenotype, and make and test predictions about the identity of mutants, are invaluable in college-level cell biology, genetics, and microbiology courses. While many bacteria are easy to grow and manipulate within the time and resource constraints of a laboratory course, their phenotypes are not always observable or relevant-seeming to college students. Here, we leverage sporulation by the bacterium Bacillus subtilis, a well-characterized and genetically tractable system, to create 5 adaptable lab exercises that can be implemented in different combinations to suit the needs of a variety of courses and instruction modes. Because phenotypic changes during sporulation are striking morphological changes to cells that are easily observable with basic light microscopy, and because spore-forming bacteria related to B. subtilis have clear applications for human and environmental health, these exercises have the potential to engage students' interest while introducing and reinforcing key concepts in microbiology, cell biology, and genetics.
