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

Mitochondrial antiviral signaling protein (MAVS) is an essential component of virus-activated signaling pathways that induce protective IFN responses. Its localization to the outer mitochondrial membrane suggests an important yet unexplained role for mitochondria in innate immunity. Here, we show that hepatitis A virus (HAV), a hepatotropic picornavirus, ablates type 1 IFN responses by targeting the 3ABC precursor of its 3C(pro) cysteine protease to mitochondria where it colocalizes with and cleaves MAVS, thereby disrupting activation of IRF3 through the MDA5 pathway. The 3ABC cleavage of MAVS requires both the protease activity of 3C(pro) and a transmembrane domain in 3A that directs 3ABC to mitochondria. Lacking this domain, mature 3C(pro) protease is incapable of MAVS proteolysis. HAV thus disrupts host signaling by a mechanism that parallels that of the serine NS3/4A protease of hepatitis C virus, but differs in its use of a stable, catalytically active polyprotein processing intermediate. The unique requirement for mitochondrial localization of 3ABC underscores the importance of mitochondria to host control of virus infections within the liver.
