Preservation of Microorganisms for Storage in Culture Collections.
Article in Methods in molecular biology (Clifton, N.J.), 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
Microbial culture collection centers are pivotal for preserving and providing microorganisms for scientific and industrial applications. Proper preservation methods, like freezing or drying, are crucial. Cryostorage in the vapor or liquid nitrogen (LN) phase at temperatures below -150°C is used to ensure that the biological material is stored genetically unaltered. In addition, microorganisms are preserved as dried lyophilizates using appropriate freeze-drying protocols, where applicable. Maintaining the quality of source material through optimal growth conditions is also essential, and can be found in species descriptions, in culture collections catalogs, or online databases. This applies in particular to microorganisms that are difficult to cultivate and is of crucial importance for preservation, but is often a challenge due to the laborious cultivation process. The protocols described in this chapter represent examples of how microorganisms in culture collections are preserved at the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures GmbH.
