Interferons in enteroviral heart disease: modulation of cytokine expression and antiviral activity.
Article in Medical microbiology and immunology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Interferon (IFN)-beta has a more than 120-fold higher antiviral activity than the closely related IFN-alpha in human myocardial fibroblasts infected with the cardiotropic enterovirus coxsackievirus B3 (CVB3). CVB3 replication induces interleukin (IL)-6 and IL-8 expression in myocardial fibroblasts, and suppresses the expression of monocyte chemoattractant protein-1 (MCP-1). We investigated whether the higher antiviral activity of IFN-beta compared to IFN-alpha was a result of a suppression of IL-8 expression by IFN-beta since previous studies had indicated that IL-8 stimulates enterovirus replication. Human myocardial fibroblasts were treated with either IFN-alpha, IFN-beta or IFN-gamma (0, 10, 100, or 1,000 IU/ml) and the concentrations of IL-6, IL-8 and MCP-1 were measured in culture supernatants by immunoassays. Both IFN-beta and IFN-gamma reduced IL-6 and IL-8 expression significantly. In addition, neutralization of IL-8 in culture supernatants of myocardial fibroblasts using a monoclonal antibody demonstrated a significant reduction of CVB3 titers. Antiproliferative effects of all three IFNs were very low (<30% with 1,000 IU/ml), indicating that the suppression IL-6 and IL-8 was not related to cytotoxicity. MCP-1 expression was increased only by high concentrations of IFN-gamma (1,000 IU/ml). By contrast, IFN-alpha had no significant effect on IL-6, IL-8 and MCP-1 expression. In conclusion, suppression of IL-8 expression is an "immuno-modulating" feature of IFN-beta in human myocardial fibroblasts, which is similar to the activity of IFN-gamma. This feature of IFN-beta contributes to its high antiviral activity against CVB3 and may be useful in the treatment of enteroviral heart disease.
