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

Coronavirus replicase polyproteins are translated from the genomic positive-strand RNA and are proteolytically processed by three viral proteases to yield 16 mature nonstructural proteins (nsp1 to nsp16). nsp4 contains four predicted transmembrane-spanning regions (TM1, -2, -3, and -4), demonstrates characteristics of an integral membrane protein, and is thought to be essential for the formation and function of viral replication complexes on cellular membranes. To determine the requirement of nsp4 for murine hepatitis virus (MHV) infection in culture, engineered deletions and mutations in TMs and intervening soluble regions were analyzed for effects on virus recovery, growth, RNA synthesis, protein expression, and intracellular membrane modifications. In-frame partial or complete deletions of nsp4; deletions of TM1, -2, and -3; and alanine substitutions of multiple conserved, clustered, charged residues in nsp4 resulted in viruses that were nonrecoverable, viruses highly impaired in growth and RNA synthesis, and viruses that were nearly wild type in replication. The results indicate that nsp4 is required for MHV replication and that while putative TM1, -2, and -3 and specific charged residues may be essential for productive virus infection, putative TM4 and the carboxy-terminal amino acids K(398) through T(492) of nsp4 are dispensable. Together, the experiments identify important residues and regions for studies of nsp4 topology, function, and interactions.
