Biological activities of C3 beta c, a novel neutrophil chemoattractant derived from the beta-chain of rat complement C3.
Article in Immunology, 1998. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Biological activities of C3 beta c, which is a C-terminal fragment of the beta-chain of rat complement C3, have been studied by in vivo and in vitro experiments. C3 beta c was purified as a novel neutrophil chemoattractant from the exudate of the chronic phase of rat carrageenin-induced inflammation. The purified C3 beta c induced neutrophil chemotaxis in vivo when C3 beta c was injected into the preformed air-pouch on the back of rats. C3 beta c transiently increased the intracellular free Ca2+ concentration of neutrophils and enhanced the adhesion of neutrophils to fibrinogen in vitro, suggesting that C3 beta c has the ability to express an adhesion molecule of rat neutrophils. In addition, C3 beta c at low concentrations (10(-10)-10(-11) M) stimulated rat macrophages to produce cytokine-induced neutrophil chemoattractant-2, a member of the interleukin-8 family. Furthermore, C3 beta c enhanced vascular permeability in vivo, which is suppressed by cyproheptadine, suggesting that C3 beta c may have the characteristics of an anaphylatoxin. Our results suggest that C3 beta c contributes to oedema formation and neutrophil accumulation at inflammatory sites in rats.
