Molecular identification of hyaluronate lyase, not hyaluronidase, as an intrinsic hyaluronan-degrading enzyme in Clostridium perfringens strain ATCC 13124.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Clostridium perfringens, an opportunistic pathogen, produces mu-toxin hyaluronidases including endo-β-N-acetylglucosaminidases (Nags) as a virulence invasion factor. To clarify an intrinsic factor for degradation of host extracellular hyaluronan, we focused on hyaluronate lyase (HysA), distinct from endo-β-N-acetylglucosaminidases. C. perfringens strain ATCC 13124 was found to assimilate host-derived extracellular mucosubstances, hyaluronan and mucin, which induced expression of the hyaluronan-related genetic cluster, including hyaluronate lyase gene (hysA), but repressed endo-β-N-acetylglucosaminidase genes. This genetic cluster is conserved in some strains of C. perfringens. The recombinant strain ATCC 13124 hyaluronate lyase HysA showed an hyaluronan-degrading activity through β-elimination reaction. The hyaluronan-degrading enzyme in the culture supernatant of strain ATCC 13124 exhibited the lyase activity and was identical to the recombinant hyaluronate lyase on the native-PAGE gel, followed by activity straining. These results demonstrated that the intrinsic hyaluronan-degrading enzyme of C. perfringens strain ATCC 13124 is hyaluronate lyase HysA, but not hyaluronidases NagH, NagJ, and NagK.
