Evaluating preservation effects on honeybee gut microbiota inocula.
Article in Microbiology spectrum, 2026. 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 honeybee ( IMPORTANCE: The gut microbes of honeybees are essential for their nutrition, immunity, and overall health. To study these microbes, scientists often use germ-free bees colonized with gut communities from donor bees. Fresh preparations are ideal, but repeated preparation is time-consuming, requires pathogen checks, and may involve sacrificing many bees. In this study, we tested practical preservation methods and found that both refrigerated and frozen samples retained the ability to colonize germ-free bees. However, one day of refrigeration preserved microbial abundance and composition most similar to fresh samples, whereas longer refrigeration and freezing introduced detectable changes. These findings provide researchers with clear guidance for preparing standardized microbial inocula while also minimizing repeated dissection of donor bees, thereby improving both experimental reproducibility and animal welfare.
