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

Hepatitis A virus (HAV) is a positive-sense RNA virus causing acute inflammation of the liver. Here, using a genome-scale CRISPR screen, we provide a comprehensive picture of the cellular factors that are exploited by HAV. We identify genes involved in sialic acid/ganglioside biosynthesis and members of the eukaryotic translation initiation factor complex, corroborating their putative roles for HAV. Additionally, we uncover all components of the cellular machinery for UFMylation, a ubiquitin-like protein modification. We show that HAV translation specifically depends on UFM1 conjugation of the ribosomal protein RPL26. Furthermore, we find that components related to the yeast Trf4/5-Air1/2-Mtr4 polyadenylation (TRAMP) complex are required for viral translation independent of controlling viral poly(A) tails or RNA stability. Finally, we demonstrate that pharmacological inhibition of the TRAMP-like complex decreases HAV replication in hepatocyte cells and human liver organoids, thus providing a strategy for host-directed therapy of HAV infection.
