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
The study of the molecular mechanisms underlying the action of immunomodulatory drugs is important for substantiating their therapeutic effect. In the present work, spontaneous and TNFα-induced secretion of IL-1α and IL-8 pro-inflammatory cytokines, as well as the level of the ICAM-1 adhesion molecule in EA.hy 926 endothelial cell culture and peripheral blood mononuclear cells of healthy donors, is studied using an in vitro model of inflammation in the presence of α-glutamyl-tryptophan (α-Glu-Trp) and Cytovir-3. The aim was to evaluate cellular mechanisms mediating the immunomodulatory effect of α-Glu-Trp and Cytovir-3 drugs. It was shown that α-Glu-Trp reduced TNFα-induced IL-1α production and increased TNFα-stimulated level of the ICAM-1 surface molecule of endothelial cells. At the same time, the drug reduced secretion of the IL-8 cytokine induced by TNFα and increased the spontaneous level of ICAM-1 in mononuclear cells. Cytovir-3 had an activating effect on EA.hy 926 endothelial cells and human peripheral blood mononuclear leukocytes. In its presence, there was an increase in the spontaneous secretion of IL-8 by endothelial and mononuclear cells. In addition, Cytovir-3 increased the level of TNFα-induced ICAM-1 on endothelial cells and increased the spontaneous level of this surface molecule on mononuclear cells. Suppression of stimulated production of pro-inflammatory cytokines under the action of α-Glu-Trp both separately and as a part of Cytovir-3 may determine its anti-inflammatory properties. However, an increased level of the surface ICAM-1 molecule indicates mechanisms that enhance the functional activity of these cells, which is equally important for the implementation of an effective immune response to infection and repair of damaged tissues during inflammatory response.
