1 · What the graph read from it

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.

2 · The registry

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

Viral infection often activates the interferon (IFN)-gamma-inducible gene, nitric oxide synthase 2 (NOS2). Expression of NOS2 can limit viral growth but may also suppress the immune system and damage tissue. This study assessed each of these effects in genetically deficient NOS2(-/-) mice after infection with influenza A, a virus against which IFN-gamma has no known activity. At inocula sufficient to cause consolidating pneumonitis and death in wild-type control mice, NOS2(-/-) hosts survived with little histopathologic evidence of pneumonitis. Moreover, they cleared influenza A virus from their lungs by an IFN-gamma-dependent mechanism that was not evident in wild-type mice. Even when the IFN-gamma-mediated antiviral activity was blocked in NOS2(-/-) mice with anti-IFN-gamma mAb, such mice failed to succumb to disease. Further evidence that this protection was independent of viral load was provided by treating NOS2(+/+) mice with the NOS inhibitor, Nomega-methyl-L-arginine (L-NMA). L-NMA prevented mortality without affecting viral growth. Thus, host NOS2 seems to contribute more significantly to the development of influenza pneumonitis in mice than the cytopathic effects of viral replication. Although NOS2 mediates some antiviral effects of IFN-gamma, during influenza infection it can suppress another IFN-gamma-dependent antiviral mechanism. This mechanism was observed only in the complete absence of NOS2 activity and appeared sufficient to control influenza A virus growth in the absence of changes in cytotoxic T lymphocyte activity.
