Immobilization of formate dehydrogenase on polyethylenimine-grafted graphene oxide with kinetics and stability study.
Article in Engineering in life sciences, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Graphene oxide-based nanomaterials are promising for enzyme immobilization due to the possibilities of functionalizing surface. Polyethylenimine-grafted graphene oxide was constructed as a novel scaffold for immobilization of formate dehydrogenase. Compared with free formate dehydrogenase and graphene oxide adsorbed formate dehydrogenase, thermostability, storage stability, and reusability of polyethylenimine-grafted graphene oxide-formate dehydrogenase were enhanced. Typically, polyethylenimine-grafted graphene oxide-formate dehydrogenase remained 47.4% activity after eight times' repeat reaction. The immobilized capacity of the polyethylenimine-grafted graphene oxide was 2.4-folds of that of graphene oxide. Morphological and functional analysis of polyethylenimine-grafted graphene oxide-formate dehydrogenase was performed and the assembling mechanism based on multi-level interactions was studied. Consequently, this practical and facile strategy will likely find applications in biosynthesis, biosensing, and biomedical engineering.
