Liver inflammation in a mouse model of Th1 hepatitis despite the absence of invariant NKT cells or the Th1 chemokine receptors CXCR3 and CCR5.
Article in Laboratory investigation; a journal of technical methods and pathology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The specific mechanisms that mediate CD4(+) T-cell-mediated liver injury have not been fully elucidated. CD4(+) invariant natural killer T (iNKT) cells are required for liver damage in some mouse models of hepatitis, while the chemokine receptors CXCR3 and CCR5 are considered dominant Th1 chemokine receptors involved in Th1 trafficking in inflammatory conditions. BALB/c-Tgfb1(-/-) mice spontaneously develop Th1 hepatitis. Here, we directly test the hypotheses that iNKT cells or the Th1-cell chemokine receptors CXCR3 and CCR5 are required for development of liver disease in Tgfb1(-/-) mice. Tgfb1(-/-) mouse livers exhibited significant increases in iNKT cells and in ligands for CXCR3 or CCR5. Tgfb1(-/-) mice were rendered deficient in iNKT cells, CXCR3, CCR5, or both CXCR3 and CCR5, by cross-breeding with appropriate knockout mice. Tgfb1(-/-) mice developed severe liver injury, even in the absence of functional CD1d/iNKT cells, CXCR3, CCR5, or both CXCR3 and CCR5. Liver CD4(+) T cells accumulated to high numbers, and spleen CD4(+) T-cell numbers declined, regardless of the functionality of the CXCR3/CCR5 response pathways. Similarly, dendritic cells and macrophages accumulated in Tgfb1(-/-) livers even when CXCR3 and CCR5 were knocked out. Th1-associated cytokines (IFN-γ, TNF-α, IL-2) and chemokines (CXCL9, CXCL10) were strongly overexpressed in Tgfb1(-/-) mice despite knockouts in CD1d, CXCR3, or CCR5. These studies indicate that the cellular and biochemical basis for CD4(+) T-cell-mediated injury in liver can be complex, with myriad pathways potentially involved.
